Tension= mg+mv^2/r
Yours is not correct.
1) A 1320 kg demolition ball swings at the end of a 34.3 m cable on the arc of a vertical circle. At the lowest point of the swing, the ball is moving at a speed of 3.32 m/s. Determine the tension in the cable.
F=ma
(34.3)(3.32) = 113.87
Ia this correct?

so m=1320kg and v=3.32^2 but what is r and mg?
r = 34.3 m,
m•g=1320•9.8 =12936 N
v^2 =(3.32)^2 =11.02
m•g=1320•9.8 =12936 N
v^2 =(3.32)^2 =11.02
