- Q1A 10-N force is exerted on a box, moving it 20 m in the same direction. According to the above diagram, what is the magnitude of work done on the box?2 J30 J10 J200 J120s112.39.c.6.a
- Q2Conveyor belts are often used to move packages around warehouses. The conveyor shown below moves packages at a steady 4.0 m/s. A 500 N employee decides to catch a ride by sitting on a 1,000 N box for a 50 m trip as shown below. What is the work done by the employee on the box shown above?500,000 J0 J1,500,000 J1,000,000 J120s112.39.c.6.a

- Q5A student examines the relationship between gravitational potential energy and position of a ball above the ground as shown in the graph below. What does the slope of the above graph represent?Potential energyAcceleration due to gravityWeightMass120s112.39.c.6.a
- Q6A tennis ball launcher works by using a spring to propel the ball forward as shown below: One model of tennis ball launcher has advertised that it is capable of imparting 15,000 J of kinetic energy to a 0.5 kg ball initially at rest. A student carefully measures the compression of the spring to be 0.10 m. What is the value of the spring constant for the tennis ball launcher according to the data provided?3,000,000 N/m3.6 X 10^13 N/m1,732 N/m6,000,000 N/m120s112.39.c.6.a
