Captain America pushes a car out of the way with 1000 N of force. He manages to move it 8 meters. How much work does he do on the car?

A figure skater slides to a stop by pushing her blades against the ice as shown. The ice exerts a constant force of 200 N on the skater, and the skater stops at 0.6 m. The angle between the force and the skater's direction of motion is 140°. What is the work done on the skater by the ice?

In the movie Independence Day (mild spoilers, but old movie) Captain Steven Hiller (played by Will Smith) pulls an alien wrapped in a parachute across the desert.  Hiller pulls the parachute/alien with a constant force of 259. N for a distance of 2.8 x 105 m.  How much work did he do?

Magnus has reached the finals of a strength competition. In the first round, he has to pull a city bus as far as he can. One end of a rope is attached to the bus and the other is tied around Magnus's waist. If a force gauge placed halfway down the rope reads out a constant 2150 Newtons while Magnus pulls the bus a distance of 1.10 meters, how much work does the tension force do on Magnus? The rope is perfectly horizontal during the pull.

A 23 N rock is dropped from a height of 11.5 m, and the velocity right before hitting the ground is 13.50 m/s. What is the work done by the air friction?

The object is being pulled in a straight line along the ground by a 50-N force directed 60° above the horizontal. How much work does the force do in pulling the object 5 m? O 530 J O 125 J 0.55 J O 125 kJ O 53 J

A 60-kilogram student climbs a ladder a vertical distance of 4.0 meters in 8.0 seconds. Approximately how much total work is done against gravity by the student during the climb? O 2.4 x 10³ J O 2.9 × 10³ J O 2.4 x 10?J O 3.0 x 10' J
