Question

a child hits a ball with a force of 350 N. (a) If the ball and bat are in contact for 0.12 is, what impulse does the ball receive? (b) what is its change in momentum?

Answer 1

A.4200Ns

Step-by-step explanation:

Impulse=Force*Time

I=F*t

350N*0.12s

=42Ns

Answer 2

Step-by-step explanation:

(a) Impulse is force times time.

J = FΔt

J = (350 N) (0.12 s)

J = 42 Ns

(b) Change in momentum is equal to impulse.

J = Δp

Δp = 42 Ns
