Homework Statement
A point mass m= 20 kg, is suspended by a
massless spring of constant 2000 N/m. The
point mass is released when elongation in
the spring is 15 cm. The equation of
displacement of particle as function of time
is : (Take g = 10 m/s2)
Homework Equations
A is amplitude
w is omega
t is time
k is spring constant
The Attempt at a Solution
PE= 1/2 m A^2 w^2 cos^2(wt+ phi)
PE=1/2Kx^2
equating these two equations doesn't do anything so how do i proceed?
