A 3kg ball is accelerated from rest to a speed of 10 m/s. What is the ball's change in momentum?

(J) momentum=mass* change in velocity

J=3kg*(10m/s-0m/s) since the object started at rest, the initial velocity =0m/s.

J=30 J

Not quite.

momentum=mass*velocity=30 Nt-m/s or J/s

Gave the wrong units, which is J/s; I apologize, I was moving too fast, but the set up is correct.
