Solve the all parts of following question:

Question: A skier of mass 79 kg is pulled up a slope by a motor-driven cable.

Part A: How much work is required to pull him 80 m up a 30Â° slope (assumed frictionless) at a constant speed of 2.9 m/s?

Part B: What power (expressed in hp) must a motor have to perform this task?

I need help to determine what power (expressed in hp) must a motor have to perform this task.
