An object has 22.4 kg•m/s of momentum. If you double the mass,
and cut the velocity in half, how
much momentum would it have?
[?] kg•m/s

Explanation:

Momentum is given by .

Let be the initial momentum of the object:

If we doubled the mass, the new mass would be , and if we halved the velocity, the new velocity would be .

Therefore, the final momentum would be:

..

the answer is a 3.8cm

explanation:

the bal will not change its velocity.
