1. The problem statement, all variables and given/known data A night somebody pushes a derelict car horizontally off a 45m high cliff top at 2.0 ms^-1. (a) How long does it take to hit the ground? (g=10ms^-2) (b) How far from the base of the cliff does it land? 2. Relevant equations The answer to (a) is 3.0s and (b) is 6.0m 3. The attempt at a solution For (a) I tried s = ut +.5at^2. Hence 45 = 2t+.5(10)t^2 but the answer was not correct.
