Compute the all parts of given problem:
Problem: A 58-kg skier starts at rest and slides 35m down a hill inclined at 12 degrees relative to the horizontal. Ignore the friction.
Part A: Determine the acceleration of the skier?
Part B: Determine the normal force exerted on the skier by the surface?
Please show complete calculations determine the acceleration of the skier thank you!
