Question

In the diagram below, a 5 kg box is pushed from rest by an applied force of 15N for 22 seconds. What was the impulse caused by this force applied? What is the final momentum?

Answer 1

Answer:

330Ns

Explanation:

Given parameters:

Mass of the box  = 5kg

Initial velocity  = 0m/s

Force applied  = 15N

Time  = 22s

Unknown:

Impulse  = ?

Final momentum  = ?

Solution:

The impulse of the box can be determined using the expression below:

     Impulse  = Force x time

    Impulse  = 15 x 22 = 330Ns

The final momentum is the same as this impulse

The impulse and the final momentum is 330Ns
