Write a custom energy statement for each question when appropriate:W=Fd P W/At PEg = magh KE = 1/2mv21. Fignewton pulls a 500. N sled along a flat snowy path using a rope. He pulls with a forceof 34.6 N on the rope. The sled moves 16.0 m in 3.00 s. What is Eignewton's poweroutput?b. Fignewton pulls the sled twice as far in twice the time, what is his power output now?2. Jewel weighs 580 N and she is sitting on a playground swing seat that hangs 0.40 mabove the ground. Nuton pulls the swing back, with Jewel on it, and releases it whenthe seat is 1.00 m above the ground.Mghi-mghf+1/2mv^2fMghi=1/2mu^2fa. How fast is Jewel moving when the swing moves through the lowest point?b. If Jewel moves through the lowest point at 2.0 m/s, how much work was done on theswing byfriction? (hint: solve for thermal energy)
