Question

E4.A force of 240.0 N acts on a ball for 0.125 s. If the ball is initially at rest:
(a) What is the impulse on the ball?
(b) What is the final momentum of the ball?

Expert Solution

Step 1

Since you are posted more than one question, we will answer the first question. If any specific question need to be answered, please re-post the question with the question number.

The expression for find impulse on the ball is

$I = F \cdot ∆ t$

Insert values in the above equation

$\begin{array}{rcl} I & = & (240 N) (0.125 s) \\ = & 30 N \cdot s \end{array}$
