If the spring is initially compressed 4.69 cm, find the launching speed of a 0.1

Question

If the spring is initially compressed 4.69 cm, find the launching speed of a 0.1 kg ball when the plunger is released. The acceleration due to gravity is 9.8 m/s2 . Friction and the mass of the plunger are negligible. Answer in units of m/s

The ball launcher in a pinball machine has a spring that has a force constant of 1.4 N/cm. The surface on which the ball moves is inclined 11.8? with respect to the horizontal. If the spring is initially compressed 4.69 cm, find the launching speed of a 0.1 kg ball when the plunger is released. The acceleration due to gravity is 9.8 m/s2 . Friction and the mass of the plunger are negligible. Answer in units of m/s
