0 N/m oscillates on a horizontal, frictionless track. At t=0, the mass is released from rest at x=10.

A 1.5-kg mass attached to spring with a force constant of 20.0 N/m oscillates on a horizontal, frictionless track. At t=0, the mass is released from rest at x=10.0cm. (That is, the spring is stretched by 10.0cm). a.) Determine the frequency of oscillations. b.) Determine the maximum speed of the mass. Where does the maximum speed occur? c.) Determine the maximum acceleration of the mass. Where does the maximum acceleration occur? d.) Determine the total energy of the oscillating system. e.) Express the displacement as a function of time. Please show me step by step do these problems and please show me all the units. Thanks!
