The fastest pitched baseball was clocked at 47 m/s. Assume that the pitcher exerted his force (assumed to be horizontal and constant) over a distance of 1.0 mm, and a baseball has a mass of 145 g. Required:
a. Draw a free-body diagram of the ball during the pitch.
b. What force did the pitcher exert on the ball during this record-setting pitch?
c. Estimate the force in part b as a fraction of the pitcher's weight.

Following are the solution to the given points:

Explanation:

For point a:

Find the schematic of the empty body and in attachment. Upon on ball during the pitch only two forces act:

The strength of the pitcher F is applied that operates horizontally. Its gravity force acting on an object is termed weight, which value is where m denotes mass, and g the acceleration of gravity.

For point b:

First, they must find that ball's acceleration. You can use the SUVAT equation to achieve that

where

Solving for a,

Calculating the mass:

Calculating the force:

 For point c:

0.195 times the pitcher's weight

Solving for W:

Now the force of Part B could be defined as the fraction of the mass of the pitcher:  

what are the options.

explanation:

overcharge is the right answer system
