An oscillating spring with mass

A 1.00 kg glider attached to a spring with a force constant 49.0 N/m oscillates on a horizontal, frictionless air track. At t = 0, the glider is released from rest at x = -2.7 cm. (That is, the spring is compressed by 2.7 cm.)
(a) Find the period of its motion.
(b) Find the maximum values of its speed and acceleration.
(c) Find the position, velocity, and acceleration as functions of time (t).

I used the equation T = 2(pi)*sqrt(M/k) to find the period of motion, but I don't known what to use for (b) or (c)
