Question

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

Answer 1

Answer:

25N

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
