Answer:
Force is classified as a push or a pull
Explanation:
To find work, you use the equation: W = Force X Distance X Cos (0 degrees)
Following the Law of Conservation of Energy, energy cannot be destroyed nor created.
So you would do 75 N x 10m x Cos (0 degrees)= 750 J
The rocket engine works on the basic principle proposed by Newton which is Newton’s Third Law.
