Compute each part of following problem given below:
Problem: A skier speeds down a smooth ski slope which is at an angle of θ = 22° with the horizontal. The mass of the skier is 77 kg. Take the downhill direction to be positive and uphill to be negative.
Part A: What net force is acting on the skier? (Indicate the direction with the sign of your answer.)
Part B: What is the acceleration experienced by the skier? (Indicate the direction with the sign of your answer.)
This is a physic problem, reply as soon as possible. Thanks.
