A 5 kg block moves with a constant speed of 10 to the right on a smooth surface where frictional forces are considered to be negligible. It passes through a
2.0 m rough section of the surface where friction is not negligible, and the coefficient of kinetic friction between the block and the rough section He is 0.2. What
is the change in the kinetic energy of the block as it passes through the rough section?
A
20 J of energy is removed from the block.
B
250 J of energy is removed from the block.
с
20 J of energy is added to the block.
D
250 J of energy is added to the block.
