1. The problem statement, all variables and given/known data Let us now consider several questions that include numeric data. A sled is being pulled along a horizontal surface by a horizontal force F of magnitude 600 N. Starting from rest, the sled speeds up with acceleration 0.08 m/s^{2} for 1 minute. Find the instantaneous power P created by force F at t=10s. Express your answer in watts to three significant figures. 2. Relevant equations P_{avg} = [tex]\frac{\Delta W}{\Delta t}[/tex] P = [tex]\frac{dW}{dt}[/tex] 3. The attempt at a solution I have solved for velocity after 10s. v = 0.8 m/s I'm stuck at where to go from here.
If I'm not mistaken, that is the formula for P_{avg}. I am trying to solve for the instantaneous power, unless you know something I don't.
I believe that the equation would hold if you used the instantaneous force and the instantaneous velocity ( which you already found ). That is what I found here : https://www.physicsforums.com/showthread.php?t=228937 Hope that helps.
