A) kinetic energy of the block at time t
B) work done by friction
C) total work done on the block
D) acceleration of the block
Correct Answer: D
Solution :
Since relative acceleration between the observers is zero, so acceleration of both the observers are same, as a result acceleration of block with respect to observers is same. Kinetic energy, work done by friction and total work done are depending on displacement and velocity of the blocks, which may be different' for both.You need to login to perform this action.
