Spectators watch a bicycle stunt rider travel off the end of a 57.5° ramp, rise to the top of her trajectory and, at that instant, suddenly push her bike horizontally away from her so that she falls vertically straight down, reaching the ground 0.525 s later. How far (in m) from the rider does the bicycle land if the rider has a mass  mrider = 58.4 kg  and the bike has a mass  mbike = 14.5 kg?  Neglect air resistance and assume the ground is level. ?m
