Force is mass times acceleration.

F = ma

where:

F = force

m = mass

v = velocity

**Given:**

m = 50 kg

v

_{1}= 5 m/sv

_{2}= 15 m/sFirst we need to find acceleration.

Acceleration is change in velocity over time. You need to have the time in order to get your acceleration. Once you have your acceleration, multiply it by the mass.
