Q. Compared to an object that does not roll, other than instead slides without friction, should a rolling object be released from same, a greater, or a lesser height in order just barely to complete the loop the loop?
Q. The accompanying diagram, a 1.00 kg sphere at point A has a potential energy of 5.0Joules. What is the potential energy of the sphere at point B, halfway down the incline?
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 tha..
