A block of mass 0.5kg moving on a horizontal frictionless surface at 2.0 m/s collides with and sticks to a massless pan attached to the end of a horizontal ideal spring whose spring constan is 32 N/m.(adsbygoogle = window.adsbygoogle || []).push({});

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

Do I use the formula x(t) = Vo/w(sinwt)-Xo(coswt). How would i use that cause i don't have a t.

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

Do I just use T=2pi(m/k)^(1/2)

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

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