A sled is tied to a tree on a frictionless, snow-covered hill, as shown in the figure. The maximum tension the string can sustain is 40.0 N. If the sled weighs 77.0 N, (a) find the magnitude of the tension force FT→ exerted by the string on the sled, and (b) find the magnitude of the normal force n→ exerted by the hill on the sled. (c) Will the string snap?
