a 0.145 kg baseball is pitched at 39 m/s is hit on a horizontal line drive straight back to the pitcher. what is the avaerage force



Answer :

13195N

FΔt = mΔv

Now Δv = 39.0 m/s- (-52.0 m/s) = 91 m/s.

52 is negative because the ball ends up traveling in the opposite direction after coming in contact with the ball.

F = 13195N

In physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity (e.g. moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newton (N). It is a standard mechanical quantity. Force is represented by the symbol F (formerly P).
