- Homework Statement
- A person pulls on a 20kg lawnmower with a force of 25.0N and moves the mower 4.50metes. The handle angle is 15* with the horizontal and μ=0.100.

What I've found:

a) Work done by person = 109J

B) Work done by friction= -85.3J

C) Find the time= ?

- Relevant Equations
- P=W/T

W= Fd

I tried using the 109 J to convert to seconds but that didn't work. I also looked through the energy equations but nothing worked. I am not sure how to find time.
