Answer to Question #203317 in Physics for Marah

Question

Mr Gaglardi finds a spring and notices that he can stretch the spring by 25 cm when applying a force of 350 N to it. He then attaches the spring to a wall as shown. He places a 10 kg box on a nearby hill and pushes it with a force of 125 N down parallel to the slope over a distance of 1.2 m. The box travels down the slope against friction, and then 6.0 m over level ground also against friction before compressing a spring and coming to rest. If the spring gets compressed by 95 cm, how high up the hill did the box start?
