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

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

$\Delta p=F\cdot\Delta t$

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
