A 5.31 kg object is swung in a vertical circular
path on a string 2.99 m long.
The acceleration of gravity is 9.8 m/s^2
If the speed at the top of the circle is
6.2 m/s, what is the tension in the string
when the object is at the top of the circle?
Answer in units of N

So for tension I thought I could just do T=MA, and then for A, A=v^2/r, but when I plugged that all in, it was wrong. Do I need to factor gravity in some how?

So basically I plugged in T=5.31((6.2^2)/2.99)
