Review. The gravitational force exerted on a baseball is 2.21 N down. A pitcher throws the ball horizontally with velocity 18.0 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 170 ms. The ball starts from rest. (a) Through what distance does it move before its release? (b) What are the magnitude and direction of the force the pitcher exerts on the ball?

Question
Review. The gravitational force exerted on a baseball is \(-F_g \hat{\mathbf{j}}\). A pitcher throws the ball with velocity \(v \hat{\mathbf{i}}\) by uniformly accelerating it along a straight horizontal line for a time interval of \(\Delta t\) = t - 0 = t.
(a) Starting from rest, through what distance does the ball move before its release?
(b) What force does the pitcher exert on the ball?
Solution
The first step in solving 5.5 problem number trying to solve the problem we have to refer to the textbook question: Review. The gravitational force exerted on a baseball is \(-F_g \hat{\mathbf{j}}\). A pitcher throws the ball with velocity \(v \hat{\mathbf{i}}\) by uniformly accelerating it along a straight horizontal line for a time interval of \(\Delta t\) = t - 0 = t. (a) Starting from rest, through what distance does the ball move before its release? (b) What force does the pitcher exert on the ball?
From the textbook chapter The Gravitational Force and Weight you will find a few key concepts needed to solve this.
