1.	A shell of mass m is moving horizontally with velocity `v_(0)` and collides with the wedge of mass M just above points A, as shown in the figure. As a consequences, wedge starts to move towards left and the shell returns with a velocity in xy-plance. The principle of conservation of momentum can be applied for A. system (m + M) along any directionB. system (m+M) along verticalC. system (m + M) horizontallyD. None of the above
Answer» Correct Answer - C In horizontal direction, net force on the system is zero. Therefore, principle of conservation of momentum can be applied for system (m+M) horizontally.

Two blocks `A` and `B` are joined by means of a slacked string passing over a massless pulley as shown in Figure. The system is released from rest and it becomes taut when `B` falls a distance `0.5 m`. a. Find the common velocity of the two blocks just after the string becomes taut. b. Find the magnitude of impulse on the pulley by the clamp during the small interval while string becomes taut.
A body of mass `1 kg` moving with velocity `1 m//s` makes an elastic one dimesional collision with an identical stationary body. They are in contact for brief time `1 sec`. Their force of interaction increases form zero to `F_(0)` linearly in time `0.5s` and decreases linearly to zero in further time `0.5 sec` as shown in figure. Find the magnitude of force `F_(0)` in newton.
