1. A student kicks a stone horizontally over the edge of a cliffwith an initial velocity of 20.3m/s. The cliff is 43.9m above abeach. (a) How far did the stone travel in the horizontaldirection? (b) What was the time of flight of the stone? (c) Whatis the magnitude of the final velocity just before impact with thebeach? (d) What is the angle of impact below the horizon measuredin degrees? 2.A plane is flying at a contant velocity of magnitude 86.5m/sat an angle of 15.5o below the horizon. When the planedecends to a height of 56.3m it releases a crate that has aparachute that fails during deployment. What is the magnitude ofthe final velocity of the crate the instant it touchs theground? . . .
