Question: (Uniform circular motion) Calculate the tension in the string with the following information: Mass of casting weight 0.008kg Mass of hanging mass 0.0568kg Median time

(Uniform circular motion) Calculate the tension in the string with the following information:
Mass of casting weight 0.008kg
Mass of hanging mass 0.0568kg
Median time for 10 revolutions 5.09s
Radius of the circular motion 0.515m

My calculations (hopefully correct):
Period T 0.509s
Velocity V 6.357m/s
Centripetal acceleration ac of the weight 78.475m/s^2
Net centripetal force Fc 0.628 m/s
