A 15 kilogram block is accelerated at 1.7 m/s2 up a frictionless plane inclined at 5 degree to the horizontal, with the speed increasing from 10 m/s to 28 m/s.

(a) Evaluate the change in the block mechanical energy?

(b) Find the average rate at which energy is transferred to block?

(c) Find the instantaneous rate of that transfer when the block speed is 10 m/s?

(d) Find the instantaneous rate of that transfer when the block's speed is 28 m/s?
