How fast must the motorcycle leave the cliff top to land on a level ground below?
A movie stunt driver on a motorcycle speeds horizontally off a 50.0 m high cliff. How fast must the motorcycle leave the cliff top to land on a level ground below, 90.0 m from the base of the cliff where the cameras are? Ignore air resistance.
From the height you can determine the time it takes for the cycle to hit the ground from y=1/2gt^2. So t = sqrt(2y/g) = sqrt (2*50/9.8) = 3.19s. Since there is no acceleration in the x direction we use v=d/t so v = 90m/3.19s = 28.2m/s
