Question

Determine the impulse required to stop a 0.145-kg baseball moving at 35.7 m/s (80.0 mi/hr)

Answer 1

Impulse = -5.177 Ns

Step-by-step explanation:

Given the following data;

Mass = 0.145-kg

Velocity = 35.7 m/s

To find the Impulse to stop the baseball;

Now, we would find the change in velocity.

`Change \; in \; velocity = final \; velocity - initial \; velocity`

Substituting into the equation above;

Change in velocity = 0 - 35.7 = -35.7m/s

`Impulse \; of \; force = mass * change \; in \; velocity`

Substituting into the formula, we have;

Impulse = 0.145 * -35.7

Impulse = -5.177 Ns

Nite: Since it's working to stop the ball, it would be negative.
