Use the following information to calculate the speed of a ball in a pinball machine at a specific location. The ball is launched by using a spring (k = 703 N/m) compressed by 9.0 cm. Consider the starting position of the ball to be its location when the spring is compressed. How fast would the 50.3 gram ball be moving at a location which is 25.5 cm higher than the starting position? Assume that the ball slides freely--no rolling.
