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

B and D

EXPLANATION

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

[tex]\Delta p=F\cdot\Delta t[/tex]

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

A. F = 30, Δt = 1.2

[tex]\Delta p=30\cdot1.2=36[/tex]

B. F = 0.1, Δt = 300

[tex]\Delta p=0.1\cdot300=30[/tex]

C. F = 6, Δt = 4

[tex]\Delta p=6\cdot4=24[/tex]

D. F = 10, Δt = 3

[tex]\Delta p=10\cdot3=30[/tex]

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