Solve the all parts of given problem:
Problem: A skier is gliding along at 4.8m/s on horizontal, frictionless snow. He suddenly starts down a 10 degree incline. His speed at the bottom is 15m/s.
Part A: What is the length of the incline?
Part B: how long does it take him to reach the bottom?
Please show solution step by step with details.
