Question

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

B). Force = 3, time = 4
C). Force = 5, time = 2
D). Force = 10, time = 1

Answer 1

A, C and D

Step-by-step 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)((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
