1. The problem statement, all variables and given/known data You push a 10 kg box up a rough ramp at a constant speed of 2 m/s. uk=0.4 Theta=15 vi-vf=0 since constant which means a=0 Questions are a. What is the rate at which you do work on the box? b. What is the rate at which gravity does work on the box? c. What is the rate at which friction does work on the box? d. What is the rate at which the net force does work on the box? 2. Relevant equations I am not certain believe I should find distance traveled first.. Then the rest of work might be simple.. W=F*d Wyou=mg sin(0)(yf-yi)-Ff Wgravity=mg cos 180(yf-yi) ma+mgsin(theta)-ukmgcos(theta) P = F*v = rate of work done x 3. The attempt at a solution Ffric= uk*mgcos(theta)= .4(10kg)(9.8)cos(15)=.380N? 2ad=vf^2-vi^2 => vf^2-vi^2*2/a which I think would = 0 so that must be wrong I think I am on the wrong track, any help would be appreciated. Thank you!
