Abaseball pitcher in good form can throw a baseball that attains a speed of 97 mi/h in a distance of 1.3 m. assume that the ball starts from rest and its mass is 0.15 kg. (a) determine the average force (in n) exerted on the ball.

108.47N

Explanation:

Hello! To solve this problem, the first thing we must do is find the acceleration of the ball taking into account that part of the rest and that it is constant, the equation that defines this movement is as follows

Vf=97mi/h=43.36m/s= final velocity

X=1.3m=Distance travelled

Vo=0m/S=initial velocity

a=acceleration

Solving

finally we remember the second law of newton that states that the product of mass by acceleration is equal to force

F=ma

where

F=force

m=mass=0.15kg

a=aceleration

F=(0.15kg)(723.11m/S^2)=108.47N

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
