Question

help!!
a 0.25kg ball is attached to the end of a string. it is swung in a vertical circle of radius 0.6m. at the top of the circle it velocity is 3m/s.
draw a free body diagram for the ball when it is at the top of the circle. next to that diagram indicate the direction of it's acceleration.
use that free body diagram to set up the equations needed to determine the tension in the string.
solve those equations for the tension in the string.
