Shot 2 Shot 1 d12
To apply the theorem of conservation of energy to solve kinetic problems.Two children are trying to shoot a marble of mass m into a small box of negligible height using a spring-loaded device; as shown, this device is bolted onto a table and shoots horizontally from the edge of the table. (Figure 1)The edge of the table is a height H above the top of the box and the center of the box is a horizontal distance d from the edge of the table. (Recall that the box has negligible height and, therefore, the top of the box is level with the floor.) The spring has a spring constant k. The first child compresses the spring a distance x1 and finds that the marble falls short of its target by a horizontal distance d12
By what distance, x2, should the second child compress the spring so that the marble lands in the middle of the box?
