How does the mass on a horizontal spring behave?

[mattmannmf]

A 53 gram mass is attached to a massless spring and allowed to oscillate around an equilibrium according to:
y(t) = 1.2*sin( 3.1415*t ) where y is measured in meters and t in seconds

(a) What is the spring constant in N/m ?

(b) What is the total Mechanical Energy in the mass/spring system?

(c) What is the maximum Kinetic Energy of the mass?

(d) What is the maximum velocity of the mass in m/s ?

What are your thoughts on how to approach it?
