The ball launcher in a pinball machine has a spring that has a force constant of 1.20N/cm . the surface on which the ball moves is inclined 10.0 degrees with respect to the horizontal. If the spring is initially compressed 5cm find the launching speed of 100g ball when the plunger is released. Friction and the mass of the plunger are negligible.
The answer should be 1.68 m/s...... How i dont know!!!, and this Q is coming n Exam and im still working on it.
Thx For helping .
