Solve the all given parts of following problem:

Problem: A skier of mass 61kg is pulled up a slope by a motor-driven cable.

Part A: How much work is required to pull him 45 m up a 30 degree slope (assumed frictionless) at a constant speed of 1.6 m/s?

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

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