Let the particle collide at time t. Projectile Motion 53 Introductory Exercise 4. At point A velocity v of the particle will be parallel to the inclined plane. Projectile Motion Differentiating Eq. As initial vertical velocities of both particles will be zero and both fall under same acceleration g.

At time t: Two values of t will satisfy Eq.. On the trajectory there be two points P and Q at height h from ground. Let t be time. Path of particle u Horizontal motion: Projectile Motion Option b incorrect. Projectile motion is uniformly accelerated everywhere even at the highest point. Option a correct.. For range to be maximum i.

At the highest point acceleration is perpendicular to velocity. Option c incorrect. Displacement First particle: For time TA taken by A to return to the point of projection: Assertion and Reason both are correct. Assertion is wrong while the explanation and as given in reason is correct. Reason for this incomplete as then TA will not be equal to TB. Thus, option c is correct. H u12V u22 V: Acceleration is nothing but rate of change of velocity written against reason is correct. Using law of conservation of mechanical.

Similarly option b is also incorrect. Option a is incorrect. Option a is incorrect.. Match the Columns 1. Substituting values of g.. N R and w pass through point O. N R and wB pass through point O. Component See figure answer to question no. For the block to be at rest w. As net downward force on the system is T zero.

On stopping 2 kg. At point P. FBD is given in the answer. F 60 If the monkey exerts a force F on the rope upwards. If monkey releases her hold on rope both monkey and bananas fall freely under gravity. For equilibrium of block. Net contact force is resultant of friction and normal reaction. Laws of Motion But if we increase F2 friction acting on the block will increase.

If we increase F1. If accelerations of both the frames are same then one frame as observed from other frame will be inertial. Force of friction is in the direction of motion.

Due to acceleration of B towards left pseudo force equal to ma will act on block. Speed of A w. For every x displacement of wedge w the vertical fall in mass would have been 2x as the string passes through pulley B.

Laws of Motion T OR As the likely movement would be towards right f2 will be at its maximum. For the equilibrium of 4 kg mass: For the rotational equilibrium of rod Option a is correct.

Just at the position of tipping off. For the rotational equilibrium of the block N 2 R1 f O B Taking moment about O. Taking moment about point O. Laws of Motion Thus.

A [Note: The cube will be just at the point of tilting about point A. The three centres of the hemisphere and that of sphere will form a tetrehadron of edge equal to 2R.

Tension in lift cable will increase when the lift is accelerated upwards]. Normal reaction between the surface and the particle will be zero throughout the motion if the path of the particle is that of a projectile motion particle is free from surface. The direction of the normal reactions String is winding on the motor shaft the B will further.

Equation to circle is Y x. F Option d is correct. As the mass is applying maximum possible force without moving.

At maximum acceleration value of a.. Increasing from zero when F attains 6 N. The system will be in equilibrium. Maximum value of friction.

See solution to Question no. Maximum value of friction available to block is less than the maximum value of friction available to man. After that. All contact forces e.. Block would be slipping in the downward direction. Between two protons field force also acts. If the body is at the point of slipping the force of force will be limiting too. Force of friction will be in the upward direction. Laws of Motion 7. Energy and Power Introductory Exercise 6.

Energy and Power 2 4. A goes down byx. In Fig. Spring get extended by x. The value of T must be greater that Mg. False Introductory Exercise True d Work done by gravity will be negative Ans. False b As some negative work will be done by Mg. When block of man M goes down by x. Conservative force field and Potential Energy.

For U to be minimum. Energy and Power For 45 kg mass to drop 12 mm. On a body placed on a rough surface if an external force is applied the static body does not move then the work done by frictional force will be zero. Energy and Power 2. KE of 12 kg mass: KE of 6 kg mass 1 1 m12v2: While ball comes down t0 O t Fig. Net work done Let x be the elongation in the spring. Due to inertia the spring will not start compressing the moment the block just touches the spring and as such the block will still be in the process as increasing its KE.

Thus v of the block will be maximum when it compresses the spring by some amount. Energy and Power 1 Work done by normal force is zero. In circular motion only the work done by 1. Assertion is false. Assertion is true. Work done by constant force F when the body shifts from A to B. If a non-conservative force acts on a particles.

A The centripetal force is zero. Conservative force has nothing to do with kinetic energy. Assertion is true and also as explained above reason besides being true is the correct explanation for the Assertion.

According to 2nd low of motion. As displacement is opposite to force reason the work done by force will be negative.

Work done by conservative force decreases PE reason is true. The velocity gained by block will take the block above its equilibrium and the block will oscillate about its equilibrium position as given in reason. When the block comes down the wedge. It will along AB as shown in figure.

Work done by all the forces is equal to change in KE is as per work-energy theorem.

The work done by the force F will be used up in doing work against friction f2 and also increasing the elastic potential energy of the cord. The Reason is false. Earth is non-inertial which is also true is a separate issue and has nothing to do with the assertion. It is true that work-energy theorem can be applied to non-inertial frame also as explained in the answer to question no. When block is depressed the excess of upthrust force will act as restoring force and will bring the block up.

There will be increase in length of the elastic cord. Reason also being the correct explanation of the assertion. Kinetic frictional force remains constant but is a non-conservative force. As explained above the reason is false. In this case the mechanical energy is being used up in doing work against friction and in increasing the PE of the block.

Downward acceleration. Let x be the expansion in the spring. Energy and Power m 4. It means KX i becomes zero. C is point of stable equilibrium.

Energy and Power i. Acceleration of the block will decrease as the block moves to the right and spring expands the velocity v of block will be maximum. KE of the block will be maximum when it is just at the point of touching the plank and at this moment there would no compression in the spring. Ui at 1. Energy and Power At this moment. Option d. Particle can't be found in the regions above PE max line. Options c and d are incorrect. When the spring attains to natural length.

If the 2 extended spring is released the energy stored in the spring will be lost when the spring attains its natural length. Cunha, C. D'Andrea, L. De Vicente, S. Desai, P. Doel, T. Eifler, B.
