If the force of friction on the crate is a steady 70 N, find the KE gained by the crate

How much work is done when you push a create horizontally with 100 N across a 10 m factory floor?

b) if the force of friction on the crate is a steady 70 N, show that the KE gained by the crate is

Answer:

300 J

Explanation:

The net work gives the kinetic energy gained. The net force will be 100 N-70 N = 30 N

Work is a product of force and distance hence

Net work=30*10=300 J

Therefore, the kinetic energy gained is 300 N. I assume the first part of the question was already answered
