A baseball has a mass of 145 g. A pitcher throws the baseball so that it accelerates at a rate of 80 m/s². How much force did the pitcher apply to the baseball?

11.6 N
0.6 N
1.8 N
65 N

1 answer

To calculate the force applied to the baseball, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a):

F = m * a

Given:
mass (m) = 145 g = 0.145 kg
acceleration (a) = 80 m/s²

Substituting these values into the formula:

F = 0.145 kg * 80 m/s²
F = 11.6 N

Therefore, the force applied by the pitcher to the baseball is 11.6 N.
