Question

Lee pushes horizontally with a force of 75 n on a 36 kg mass for 10 m across a floor. calculate the amount of work lee did. answer in units of j.

Answer 1

The amount of work Lee did is 750 Joules.

Step-by-step explanation:

Work is calculated by multiplying the force exerted on an object by the distance it is moved. In this case, Lee exerts a horizontal force of 75 N on a 36 kg mass, moving it for a distance of 10 m. Therefore, the work done by Lee can be calculated as:

Work = Force × Distance

Work = 75 N × 10 m

Work = 750 J

So, the amount of work Lee did is 750 Joules.

Answer 2

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
