A 0.25 kg baseball is in contact with a bat for 0.0075 s and exerts a force of 18,500 N. What impulse is delivered to the ball?

33 kg • Meters per second.
140 kg • Meters per second.
4600 kg • Meters per second.
74,000 kg • Meters per second.

Answer:To calculate the impulse delivered to the ball, you can use the formula for impulse:

Impulse = Force × Time

Given:

- Force = 18,500 N

- Time = 0.0075 s

Now, you can plug in these values into the formula to find the impulse delivered to the ball.

Answer:

138.75 Ns

Explanation:

Certainly! We can calculate the impulse delivered to the baseball using the formula for impulse:

Impulse (J) = Force (N) × Time (s)

Here's what we know:

Mass of the baseball (m) = 0.25 kg

Force applied (F) = 18,500 N

Time of contact (t) = 0.0075 s (given in the prompt)

We are solving for the impulse (J).

Now, let's plug the values into the formula:

Impulse = Force × Time

Impulse = 18,500 N × 0.0075 s

Impulse = 138.75 Ns (Newton-seconds)

Therefore, the impulse delivered to the baseball is 138.75 Newton-seconds.
