Question

A basketball has a mass of 1 kg and is traveling 12 m / s . How fast would a 6 kg bowling ball have to travel to have the same momentum ?

a. 1 m/s
b. 2 m/s
c. 3 m/s
d. 4 m/s

Answer 1

B. 2m/s

Answer 2

First you need to calculate the momentum of basketball:
p = m*v
Here, m = 1 Kg
v = 12 m/s

Substitute in into the equation,
P = 1*12 = 12 Kgm/s

Now, another ball has mass 6 Kg. So, for same momentum it's velocity would be:
P = m*v
12 = 6*v
v = 12/6
v = 2 m/s

So, option B is your answer!

Hope this helps!
