Answer:
15 kg m/s
Step-by-step explanation:
p=mv
p= momentum
m=mass
v=volume
SO momentum (p)= 5kg (mass) x 3m/s (velocity) = 15 kg m/s
Also careful, because velocity is a vector quantity, so it has both magnitude
AND direction- but we can't include direction because there was none given in the problem.
I hope this helps!
