A 15 kg block is accelerated at 17 ms2 up a frictionless


A 15 kg block is accelerated at 1.7 m/s2 up a frictionless plane inclined at 5.0° to the horizontal, with the speed increasing from 10 m/s to 35 m/s.

(a) What is the change in the block's mechanical energy?

J

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

W

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

W

(d) What is the instantaneous rate of that transfer when the block's speed is 35 m/s?

W
