For the mechanism
shown , with the ball revolving with 5 m radius , find the velocity of
the ball and the tension in the cord. The length of the cord is 10 m ,
while the mass of the ball is 2 kg. The unstretched length of the spring
is 4 m and the spring stiffness is k = 10 N/m.
= R/L = 5/10 =0.5.
The equations of motion
for the ball are as follows-
