Work performed = Force x displacement = 100 x 5 = 500 J (joule)
The idea is to multiply the force times the distance. This implies that:a) The force is constant
b) The force and the movement are in the same direction
It goes across.
friction
Friction force = -F The crate is at rest, so all forces must be balanced
0 since the speed is constant
intertia takes place

You push against the floor; the floor pushes against you - in the opposite direction.

Work = force x distance Work = 55 x 4 = 220J
Work done = force x mass . gotcha
You are ina jumbo jet moving at 600km/hr you jump streight up where do you land?
