Physics (AS & A Level) · May / June 2016 · Paper 11 · Question 7

A student uses a spring gun to launch a steel ball with a constant horizontal velocity. He varies the height $h$ of the gun and measures the horizontal displacement $r$ of the ball when it hits the ground. Which graph shows the variation with height $h$ of the horizontal displacement $r$?

1. AGraph A: r against h, curve starting at origin with decreasing gradient (concave down)
2. BGraph B: r against h, curve starting at origin with increasing gradient (concave up)
3. CGraph C: r against h, curve starting at non-zero r with increasing gradient
4. DGraph D: r against h, straight line through origin
