frictionless block of mass 1.65 kg is attached to an ideal spring with force constant 340 N/m . At t=0 the spring is neither stretched nor compressed and the block is moving in the negative direction at a speed of 12.7 m/s .
A-Find the amplitude.
B-Find the phase angle.
There are standard equations for this...I assume you have them. What is troubling you on this?
