5. The ball launcher in a pinball machine has a spring that has a force constant of 1.20 N/cm . The surface on which the ball moves is inclined 10.0 with respect to the horizontal. The spring is initially compressed 5.00 cm. Find (a) the launching speed of a 100-g ball when the plunger is released; (b) How far does the ball move along the incline? Friction and the mass of the plunger are negligible.
