Force After they are finished swinging, Tyler and Kelly
Chapter , Problem 62(choose chapter or problem)
Force After they are finished swinging, Tyler and Kelly decide to rollerskate. They come to a hill that is inclined at 8.5. Tyler pushes Kelly halfway up the hill and then holds her there (Figure 14). If Kelly weighs 58.0 pounds, find the magnitude of the force Tyler must push with to keep Kelly from rolling down the hill. (We are assuming that the rollerskates make the hill into a frictionless surface so that the only force keeping Kelly from rolling backwards down the hill is the force Tyler is pushing with.)
