A person pulls a toboggan for a distance of 41.6 m along the snow with a rope directed 33.8 ° above the snow. The tension in the rope is 107 N.
(a) How much work is done on the toboggan by the tension force?
(b) How much work is done if the same tension is directed parallel to the snow?
A boy shoves his stuffed toy zebra down a frictionless chute, starting at a height of 1.67 m above the bottom of the chute and with an initial speed of 1.97 m/s. The toy animal emerges horizontally from the bottom of the chute and continues sliding a..
