Question Description:

25.50

A 67.3 kg sled starts at rest on a horizontal road. The coefficient of kinetic friction between the sled and the road is μk = 0.202. A man pulls the sled a distance 5.07 m along the ground by exerting a constant force of magnitude 532 N on a rope that makes a 28.2o angle above the horizontal. Find: a) the magnitude of the normal force exerted by the ground on the sled N b) the total work done by the man J c) the work done by the frictional force on the sled J d) the speed of the sled after it has moved 5.07 m m/s e) the rate at which the man is doing work after the sled has moved 5.07 m W,all answers incorrect, please recheck and check back to me by 6 pm sharp,you didn’t incorporate the sin or cos of the angle

Answer

25.50
