A skier starts from rest down a slope 500.0 m long. The skier accelerates at a constant rate of 2.00 m/s squared. • a. Find the velocity of the skier at the bottom of the slope. Do this by deriving two separate equations for time and then making the expressions equal to each other to solve for the second velocity. • b. Using the distance down the hill, and the two velocities, determine the time it took to descend the hill.
