Question

A mother pushes her 190 N child, who is sitting on a swing. If the mother exerts a 16 N force on the child for 2.50 s, what is the magnitude of the impulse imparted to the child by the mother?

Answer 1

40 Ns

Step-by-step explanation:

From the question,

Applying the formula of impulse,

I = Ft................. Equation 1

Where I = magnitude of the impulse impacted to the child by the mother, F = Force exerted on the child by the mother, t = time of impact of the force on the child.

Given: F = 16 N. t = 2.50 s

Substitute these values into equation 1

I = 16×2.5

I = 40 Ns

Hence the impulse impacted to the child by the mother is 40 Ns
