A puck of mass m 0.085 kg is going in a circle on a horizontal frictionless surface. It is held in its orbit by massless string of length L = 0.84 m. The puck makes one revolution every t = 0.55 s. 50%

What the magnitude of the tension in the string, F, in Newtons, while it spins?

Magnitude of tension

= centripetal force

= m ω²R

= m (2π/T) ² R, T is time period of revolution.

=.085 x (2 x 3.14 /.55) ² x. 84

= 9.3 N.
