The ball launcher in a pinball machine has a spring that has a force constant
of 1.20 N/cm (Figure 2.6). The surface on which the ball moves is inclined
10.0° with respect to the horizontal. If the spring is initially compressed 5.00
cm, find the launching speed of a 100 g ball when the plunger is released.
Friction and the mass of the plunger are negligible
