Question

Velocity of We assume that for 0 t t0, where t0 is the duration of the impact, the magnitude F of the force exerted on the ball can be expressed as F = Fm sin( pi t/t0). Knowing that t0 = 0.5 ms, determine the maximum value Fm of the force exerted on the ball. The triple jump is a track-and-field event in which an athlete gets a running start and tries to leap as far as he can with a hop, step, and jump. Shown in the figure is initial hop of the athlete. Assuming that he approaches the takeoff line from the left with a horizontal velocity of 10 m/s, remains in contact with the ground for 0.18 s, and takes off at a 50 degree angle with a velocity of 12 m/s, determine the vertical component of the average impulsive force exerted by the ground on his foot. Give your answers in terms of the weight W of the athlete. The last segment of the triple jump track-and-field event is the
