Answer to Question #45776 in Mechanics | Relativity for Aliwa Maher
Question #45776
A spring of stiffness 2o KN/m supports a mass of 4 Kg. the mass is pulled down 8 mm and released to produce linear oscillations. calculate the frequency and periodic time. sketch the graphs of displacement, velocity and acceleration. calculate the displacement, velocity and acceleration 0.05 s after released.
note X= A sin(w t + phase angle)
X : displacement
A : amplitude
w : omega
t : periodic time
ceta : phase angle
