A 2.0 kg block at rest is accelerated uniformly across a floor to a speed of 10 m/s in 3.0 s. The coefficient of kinetic friction between the block on the floor is 0.15.

a. How much work is done on the block by the accelerating force in the 3.0s interval?

b. What is the instantaneous power due to that force at the end of the interval?

c. What is the average power done by the force throughout the interval?
