what is the distance from the base of the cliff to the impact point where the car hits the ground?

Question

A car drives horizontally off the edge of a cliff that is 78.4 m high. The police at the accident scene make an initial guess that the car drove off the cliff with a speed 22.8 m/s. what is the distance from the base of the cliff to the impact point where the car hits the ground? 

Answer 1

v_0y= 0 and v_0x = 22.8m/s h=78.4 m To find the car's travel time to the ground use the following equation.

78.4 = gt²/2 where g=9.8 m/s² so t = √ 78.4/4.9 = 4 sec The horizontal distance traveled is x =v_0xt.

so x= 22.8•4 m = 91.2 m which is the impact point of where the car hits the ground
