A person pulls a 11-kg toboggan for a distance of 3.5 m on ahorizontal sheet of ice (frictionless) with a rope directed 25.0ºabove the horizontal snowy surface. The tension in the rope is 88N. There is also a zephyr (soft gentle breeze) in the oppositedirection of the motion applying a 11.0 N force.
(a) How much net work is done on the toboggan by ALL the forcesacting on it?
(b) If the toboggan starts from rest, how fast is it movingafter the 3.5 m distance?
(c) Use Dimensionality sense-making to check the expression youderive in part (b).
