A long jumper as shown in the figure leaves the ground at, Ask an Expert

Academics

A long jumper (as shown in the figure) leaves the ground at an angle of 17.0° to the horizontal and at a speed of 10.6 m/s.

(a) How long does it take for him to reach maximum height?

(b) What is the maximum height?

(c) How far does he jump? (Assume that his motion is equivalent to that of a particle, disregarding the motion of his arms and legs.)
