Question

Students launch a steel ball horizontally from a tabletop.
The initial horizontal speed of the ball is v, the tabletop height above the floor is H.
The objective is to get steel ball into the coffee can of height h.
Calculate the distance D at which the students need to place the can to make a
"bulls-eye".
v = 6 m/s
H = 7 m
h = 0.17 m
