a 15kg block is accelerated at 2.4m/s^2 up a frictionless plane inclined at 5 degrees to the horizontal, wth the speed increasing from 10m/s to 35m/s.
a) what is the change in the blocks mechanical energy?
b) what is the average rate at which energy is transferred to the block?
c) what is the instantaneous rate of the transfer when the blocks speed is 10m/s?
d) what is the instantaneous rate of that transfer when the blocks speed is 35m/s?
