Kinetic energy (Force and d(x))

1. The problem statement, all variables and given/known data

If no energy is dissipated , how much KE does an object gain if
a) A 10N force is applied for 5m
b) A 20N force is applied for 2m

2. Relevant equations



3. The attempt at a solution
I know there is work being done if an object moves causing it to have KE. I think work is Force * displacement and the units for Force (N) and displacement (m) works out to Joules. So does that mean I use multiply force and displacement to find the amount of KE gained?
