Question

the impulse given to a ball with a mass of 2.0 kg is 16 N.s. If the ball were already moving at 3.0 m/s, what would the final velocity be?

Answer 1

11 m/s

Step-by-step explanation:

Impulse equals change in momentum.

I = Δ(mv)

Since mass isn't changing:

I = m Δv

16 Ns = (2.0 kg) (v - 3.0 m/s)

v = 11 m/s
