D1 PBL: Gravitational potential support
A 1kg ball is at the bottom of the 10m deep, round hole shown in the image. The ball is pushed out of the hole at constant speed by exerting a force in the horizontal direction. By copying the image into LoggerPro you can analyse the curve to find that it's equation is y = 0.5x2 -10 To calculate the works done as the ball is pushed up the slope you need to know the gradient at each point. differentiating the function...
