Question

Select all of the following that equal an impulse of 10 units A).Force = 20, time = 1/2

Answer 1

Answer:

A, C and D

Explanation:

The impulse is defined as the product between the force (F) and the time of the collision (t):

$I=Ft$

Let's apply the formula to calculate the impulse for each situation:

A) $I=Ft=(20)(\frac{1}{2})=10$

B) $I=Ft=(3)(4)=12$

C) $I=Ft=(5)(2)=10$

D) $I=Ft=(10)(1)=10$

We see that the situations in which the impulse is equal to 10 units are:

A, C and D
