Passage / Comprehension
A 100 kg block is started with a speed of 4.0 m/s on a long, rough belt kept fixed in a horizontal position. The coefficient of kinetic friction between the block and the belt is 0.40.
Consider the situation from a frame of reference moving at 4.0 m/s 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 4.0 m/s. The increase in the kinetic energy of the block as it stops slipping past the belt is
Options:
Answer:
B
Solution:
In the frame moving at 4 m/s: .
