Find the tension in the string at the end of one revolution

Reference no: EM13326893

A small puck of mass m=0.1kg moves in a circle of radius 0.3m on a table top; the puck is tied with a massless string to a tether at the origin. The coefficient of kinetic friction between the puck and the table top is uk=0.25. At t=0s, the puck is moving in the vertical direction with velocity 8m/s.

a) What is the tension in the string at t=0s?

b) What is the tension in the string at the end of one revolution?
