Problem 7. A car (drawn as a solid box) initially at rest slides down a steep hillside and then falls off a cliff. On the hillside (which can be treated

as one-dimensional motion since it is a straight line), assume that the car has an acceleration whose magnitude is 4 m/s?. Once it leaves the cliff,the car is certainly undergoing projectile motion and is subject only to gravity. (a) Determine the distance it lands from the cliff R. Use D = 50 m, 0 = 30° and H = 100 m. (b) Graph horizontal position, vertical position, horizontal velocity, vertical velocity, horizontal acceleration and vertical acceleration as a function of time for the time period when it is in projectile motion. You should have the time axes for these graphs lined up.
