Its velocity is 20 cm / s when x =. 50 cm. (a) What is the amplitude of oscillation? (b) What is the balls maximum acceleration? (c) What is the balls position when the acceleration is maximum? (d) What is the speed of the ball when x = 3 . 0 cm? Problem 5 A 300 g oscillator has a speed of 95 . 4 cm / s when its displacement is 3 . 0 cm and 71 . 4 cm / s when its displacement is 6 . 0 cm.
