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 degree with respect to the horizontal. If the spring is initially compressed 5.2 cm, Find the magnitude of the launching velocity of a 100-g ball when the plunger is released. Both the mass of plunger and friction are not important here.
