A block is thrown with a velocity of `2m//s^(-1)` (relative to ground) on a belt, which is moving with velocity `4ms^(-1)` in opposite direction of the initial velocity of block. If the block stops slipping on the belt after `4sec` of the throwing then choose the correct statements `(s)`

A

Displacement with respect to ground is zero after 2.66 and magnitude of displacement with respect to ground is 12 m after 4 sec.

B

A block lying on a long horizontal conveyer belt moving at a constant velocity receives a velocity v_(0) = 5m//s relative to the ground in the direction opposite to the direction of motion of the conveyer. After t = 4s , the velocity of the block becomes equal to the velocity of the belt. The coefficient of friction between the block and the belt is mu = 0.2 . Determine the velocity v of the conveyer belt.

A 100 kg block is started with a speed of 2.0 m s^(-1) on a long, rough belt kept fixed in a horizontal position. The coefficient of kinetic friction between the block and the belt is 0.20. (a) calculate the change in the internal energy of the block=-belt system as the block comes to a stop on the belt. (b) consider the sutuation from a frame of reference moving at 2.0 m s^(-1) along the initial velocity of the block. as seen from this frame, the block is gently put on a moving belt and in due time the block starts moving with the belt at 2.0 m s^(-1) , calculate the increase in the kinetic energy of the block as it stops slipping past the belt. (c ) find the work done in this frame by the external force holding the belt.
