Question

Spectators watch a bicycle stunt rider travel off the end of a 55.0° ramp, rise to the top of his trajectory and, at that instant, suddenly push his bike horizontally away from him so that he falls vertically straight down, reaching the ground 0.600 s later. How far (in m) from the rider does the bicycle land if the rider has a mass mrider = 70.0 kg and the bike has a mass mbike = 13.5 kg? Neglect air resistance and assume the ground is level.

Answer 1

Answer: 15.27 m.

Solution:-

we will first apply linear Kinamatics to find the riders maximum height. So the maximum height by the bicycle rider system will be given by -
