Assignment:
An essentially massless spring is connected to the ceiling. A 5.00 g mass is attached to the spring so that the spring is 2.00 cm longer than its unstretched length. The mass is the pulled downward so that it is 20 cm below the equilibriun position and released from rest. After 10s the amplitude of oscillation has been reduce to 15 cm, dut to the viscous drag of the air. The equation of motion is x(t) = A0e ^-bt/2m cos (omega)ot.
(a) Determine the value of b k and omega
Find the expression for velocity as a function of time.
Derive an expression for the net force on the mass as a function of time.
