It took 30 Joules to push a box 5.0 meters across the floor. With what force was the box pushed?
To calculate the force applied to push the box, you can use the formula:
Force = Work / Distance
In this case, the work done (or energy used) to push the box is 30 Joules, and the distance the box was pushed is 5.0 meters.
Force = 30 Joules / 5.0 meters
Force = 6 Newtons
Therefore, the force applied to push the box was 6 Newtons.
