As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 17.3 m/s. in the process, he moves his hand through a distance of 1.43 m. the acceleration of gravity is 9.8 m/s 2 . if the ball has a mass of 0.196 kg, find the force he exerts on the ball to give it this upward speed. answer in units of n.

The force exerted on the ball to give it this speed is 18.6 N.

The given parameters;

The acceleration of the ball is calculated as;

The force exerted on the ball to give it this speed is calculated as;

Thus, the force exerted on the ball to give it this speed is 18.6 N.

While still in his hand, for the ball to attain a speed of 17.3 m/s over 1.43 m would require that the throw takes

Then the (presumably constant) acceleration the pitcher applies to the ball is

The total acceleration acting on the ball is then

With a mass of , the force applied to the ball would be

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.
