You are designing a pinball machine and want to test the launching mechanism. The steel pinball you use is 400 [g] and a spring launcher that has a spring constant of 1.2 [N]/[cm]. You decide to incline your machine at 15 [degrees] and the coefficient of friction between steel and all surfaces is 0.2. You pull the launcher by 10 [cm] and launch the ball up the incline. Assume g = 10 [m]/[s]^2 Useful Trigonometric formulas: cos[a - b] = cos[a]*cos[b] + sin[a]*sin[b] sin[a - b] = sin[a]*cos[b] - cos[a]*sin[b]
