Question: A 180 g block attached to a spring with spring constant 2.0 N/m oscillates horizontally on a frictionless table. Its velocity is 20 cm/s when x0 = -4.8 cm .
a) What is the amplitude of oscillation?
b) What is the block's maximum acceleration?
c) What is the block's position when the acceleration is maximum?
d) What is the speed of the block when x1 = 3.3 cm ?
