Question

If a crane uses 500 Joules to raise bricks 20 meters how much Newton’s of force were used

Answer 1

25N

Step-by-step explanation:

Given parameters:

Potential energy expended = 500J

Height = 20m

Unknown:

The force used = ?

Solution:

To solve this problem, we use the expression below:

Potential energy = Force applied x height

500 = Force applied x 20

Force applied = 25N
