Question

a force of 12N acts for 5 s on a mass of 2 kg. What is the change in momentum of a mass of 10kg under the same condition​

Answer 1

The change in momentum is: 60 N.s

Explanation:

By Newton's second law:

F = ∆p / ∆t

Given that

• ∆t = 5s

• F = 12N

Using the formula to determine the change in momentum

F = ∆p / ∆t

∆p = F × ∆t

= 12 × 5

= 60 N.s

Therefore, the change in momentum is: 60 N.s
