a) Determine the function for x(t), the displacement from equilibrium position as a function of time.

I got this to be x(t) = .25sin(8t)

b) What is the period T, of the subsequent oscillations?

I got the period to be .785 sec

c) What is the kinetic energy of the mass 4.0 sec after it collides with the spring?

I got this to be .997j

d) What force is exerted by the spring on the block at t=1.2 sec? Which way is the block moving? Explain

I got the force to be -1.334N

ARE MY ANSWERS RIGHT, I ALSO SAID THAT Xo=0m when using my equation.
