Question

A ball is kicked directly toward a fence from a point x=32m away, as shown. The velocity of the ball as it leaves the kicker’s foot is 20 m/s at an angle of 37 degrees above the horizontal. The top of the fence is h=2.5m high. The ball hits nothing while in flight and air resistance is negligible. -Determjne the maximum height of the ball during its flight. At the top of the path, Vy=0.

-Determjne the maximum height of the ball during its flight. At the top of the path, Vy=0.

Explanation / Answer

Given,

Initial velocity, u = 20 m/s

Angle, theta = 37°

Maximum height, h = u2 sin2theta / 2g = 202 x sin2 37°/ 2 x 9.81 = 7.38 m
