Question

Select all of the following that are equal to an impulse of 30 units.

A. Force = 30, time = 1.2
B. Force = 0.1, time = 300
I C. Force = 6, time = 4
D. Force = 10, time = 3

Answer 1

B and D

Step-by-step explanation

The impulse is the product of the force applied to an object and the amount of time the force is applied

`\Delta p=F\cdot\Delta t`

Let's find the impulse with the information on each option.

A. F = 30, Δt = 1.2

`\Delta p=30\cdot1.2=36`

B. F = 0.1, Δt = 300

`\Delta p=0.1\cdot300=30`

C. F = 6, Δt = 4

`\Delta p=6\cdot4=24`

D. F = 10, Δt = 3

`\Delta p=10\cdot3=30`

The options that have an impulse equal to 30 are B and D
