Homework Statement
[/B]
A 10kg bowling ball is moving with a velocity of -3m/s.
a) What is the momentum of the bowling ball?
b) What impulse must act on the bowling ball to bring it to a stop?
Homework Equations
momentum=mv
impulse=ΣFΔt
ΣFΔt=mΔv
The Attempt at a Solution
a) momentum = mv
momentum = (10)(-3)
momentum = -30Ns
b) This is where I get stuck. Is the impulse simply equal and opposite to the momentum? Or is there another step?
ΣFΔt=mΔv
ΣFΔt=-30Ns
ΣFΔt=30Ns (opposite sign because bowling ball has to be stopped by a force going in the other direction)
