A cart of mass 320 gram is located on a frictionless horizontal air track. A spring having a spring constant of 8.5 N/m is attached between the cart and the left end of the track. The cart is displaced 4 centimeter from its equilibrium position.
(a) Determine the period at which it oscillates.
__________s
(b) Determine its maximum speed.
__________m/s
(c) Determine its speed when it is located 2 centimeter from its equilibrium position.
