Answer:

The magnitude of the average force to supply to the ball in order to stop the ball is 9.68 N.

Explanation:

Let's think Newton's 2nd Law: F = ma.

We are given the mass of the ball: 219 g ⇒ .219 kg.

We are given the initial velocity, time, and final velocity of the ball ∴ we can solve for acceleration.

We are trying to find the force needed to stop the ball.

Let's find the acceleration of the ball first.

Now, we can plug these known values into this kinematic equation and solve for acceleration, a.

Substitute acceleration and mass into F = ma and solve for the force.
