Question

You want to hit a small box on the floor with a marble fired from a spring-loaded gun that is mounted on a table. The target box is a distance R horizontally from the edge of the table;see the figure. You compress the spring a distance d, but the center of the marble falls short by a distance r of the center of the box. How far (x) should you compress the spring to score a direct hit (neglect friction)? (A) x = d^2/(R-r) (B) x = d(R - r)/R (C) x = d(R - r)/(R + r) (D) x = Rd/(R - r)
