Compute all parts of given problem:
Problem: A snow skier is racing down a 50-degree slope. If there is no friction between the skis and the snow,
Part A: What is the component of the acceleration of gravity that causes the skier to move down the slope?
Part B: How long will it take the skier to complete a 2-kilometer race down the slope, assuming he begins the race with an initial velocity of zero?
I need help to determine the component of the acceleration of gravity that causes the skier to move down the slope.
