A 59 g ball attached to a spring with spring constant 2.9 N/m oscillates horizontally on a frictionless table. Its velocity is 15.4 cm/s when x=-4.79 cm.
(a) What is the amplitude of oscillation?
(b) What is the ball's maximum acceleration?
(c) What is the ball's position when the acceleration is maximum?
(d) What is the speed of the ball when x=2.42 cm?
