a 2 kg frictionless block is attached to an ideal spring with force constant 300N/m. at t=0 the spring is neither stretched nor compressed and the block is moving in the negative direction at 12m/s. find a) the amplitude and b) the phase angle, c) write a equation for the position as a function of time.

You know the total energy (which is the starting KE). AT max stretch, you now know PE, solve for amplitude. Phase angle? if you write the equation as a sine function, you know it is either zero or 180 deg, but since is goes negative at the start, the phase angle must be....
