A student pushes on a desk with a horizontal force of 125 N and moves the desk 3.2 m directly across the floor. How much work is done?
work= force*distance
To find the work done, we can use the equation W = Fd, where W is the work done, F is the force applied, and d is the distance moved.
In this case, the student pushes on the desk with a force of 125 N and moves it a distance of 3.2 m.
Therefore, the work done can be calculated as:
W = 125 N * 3.2 m = 400 J
So, the student does 400 Joules of work on the desk.
