QUESTION 1 A B с A biker + bike of combined bike + person mass 63.7 kg wants to perform a particular stunt. They will start at (A), travel up the ramp (B), and across (C), before launching and landing. The biker will leave (C), 4.47 m above the ground, perfectly horizontally. The biker must clear some water that stretches 6.52 m forward from the base of (C). See the diagram for the path the biker must take. The biker will not pedal past (A), so the kinetic energy at (A) is all they have. Friction is negligible, so mechanical energy is conserved. Calculate the minimum amount of kinetic energy needed at (A) so that the biker just passes the water,
