Question

A baseball with a mass of 142 grams is thrown across a field. It accelerates at a rate of 8 m/s^2. What is the force acting on the ball?

Answer 1

F = 1.14 N

Explanation:

Let F be the force acting on the baseball and let m = 142 g = 142×10^-3 kg and a = 8 m/s^2.

Then according to Newton's second Law of motion, the force is given by:

F = m×a

= (142×10^-3)×(8)

= 1.136 N

Therefore, the force acting on the baseball is 1.14 N.
