A 534 g mass is connected to a light spring of force constant 6 N/m that is free to oscillate on a horizontal, frictionless track. The mass is displaced 2 cm from the equilibrium point and released from rest. What is the maximum speed of the mass? What is the maximum acceleration of the mass? I found the period to be 1.87 Now I don't know what formula to use for the maximum speed, or to find the maximum acceleration.
