A block of mass 2.50 kg is pushed 2.40 m along a frictionless horizontal table by a constant 10.0 N force directed 25.0° below the horizontal.
(a) Determine the work done by the applied force.

(b) Determine the work done by the normal force exerted by the table.

(c) Determine the work done by the force of gravity.

(d) Determine the work done by the net force on the block.
2. A skier starts from rest at the top of a hill that is inclined at 9.5° with the horizontal. The hillside is 150 m long, and the coefficient of friction between snow and skis is 0.0750. At the bottom of the hill, the snow is level and the coefficient of friction is unchanged. How far does the skier glide along the horizontal portion of the snow before coming to rest?
