How much work does a supermarket checkout attendant do on a can of soup he pushes 0.600 m horizontally with a force of 5.00 N ? Express your answer in joules and kilocalories A

person climbs stairs, gaining 2.50 meters in height. Find the work done to accomplish this task. (Neglect friction in your calculations.) (a) Calculate the work done on a

elevator car by its cable to lift it 40.0 m at constant speed, assuming friction averages 100 N . (b) What is the work done on the lift by the gravitational force in this process? (c) What is the total work done on the lift Using energy considerations, calculate the average force a

sprinter exerts backward on the track to accelerate from 2.00 to

in a distance of 25.0 m , if he encounters a headwind that exerts an average force of 30.0 N against him. A

sprinter starts a race with an acceleration of

. What is the net external force on him?
