Question

Calculate the speed of a 2-kg ball that has momentum of 10 kg•m/s

Answer 1

The formula for momentum is:
M=Mass*Velocity

From this formula we can derive the formula for velocity:

V=Momentum/Mass

We already know momentum (10 kg m/s) and mass (2 kg). Let's plug in the numbers into the formula:

V=10/2
V=5 m/s
