- 1. 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.69. An external force moves a 3.50-kg box at a constant speed up a frictionless ramp (Figure 6-46). The force acts in a direction parallel to the ramp. (a) Calculate the work done on the box by this force as it is pushed up the 5.00-m ramp to a height of 3.00 m. (b) Compare the value with the change in gravitational potential energy that the box undergoes as it rises to its final height. Example 6-10 5.00 m F V 3.50 kg Figure 6-46 Problem 69 T 3.00 m3. How much work is done by a force of 50 N that acts on the block at an angle of 35 ° from the horizontal surface if the block moves horizontally at a distance of 7 meters?
