A child holds a sled at rest with a light rope on a frictionless
snow
covered hill. The
weight of the sled is 100N. The hill makes an angle of 35.0°
relative to the horizontal. (a)
Calculate the magnitude of the force that the child must exert
on the rope to hold the
sled (b) Calculate the magnitude of the normal force that the
hill exerts on the sled.
