People keeps giving me the wrong answer.
Analyzing Newton's 2^nd Law for a mass spring system, we found a_x = -k/m X. Comparing this to the x-component of uniform circular motion, we found as a possible solution for the above equation: x = Acos(omega t) v_x = - omega Asin(omega t) a_x = - omega^2 Acos(omega t) with omega = square...

A spring, of negligible mass and which obeys Hooke's Law,
supports a mass M on an incline which has negligible friction. The
figure below shows the system with mass M in its equilibrium
position. The spring is attached to a fixed support at P. The
spring in its relaxed state is also illustrated. Mass M has a value
of 255 g. Calculate k, the spring constant. The mass oscillates
when given a small displacement from its equilibrium position along
