(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Using a force of 12.0 Newtons, a student pulls a 50.0 Newton weight along the table top for a distance of 10.0 meters in 4.0 seconds. Compute the power developed by the student.

2. Relevant equations

W=Fcos(theta)d

P=W/t

3. The attempt at a solution

W=(12.0)(cos(50))(10)

W=115.8 J

P=115.8/4.0

P=28.95 J/s
