a car travels at 25m/s on a flat stretch of road. The driver must maintaint he pressure on the accelerator to keep the care moving at this speed. What is the net work done on the car over a distance of 250m?

1 answer

the net work done on the car, by the driver, is ZERO

the force is applied internally to the moving reference frame of the car

this would be like sitting in a wagon and trying to move it by pushing on the inside -- no net work
