Asled is tied to a tree on a frictionless, snow-covered hill, as shown in fiqure (a). if the sled weighs 66.0 n, find the magnitude of the tension force t exerted by the rope on the sled and that of the normal force n exerted by the hill on the sled. t= n 1= getting started i i'm stuck exercise hints: use the values from practice it to you work this exercise. suppose a child of weight w climbs onto the sled. if the tension force is measured to be 60.5 n, find the weight of the child and the magnitude of the normal force acting on the sled.
