Hey everyone, I just need help with a problem that is giving me trouble. I have scoured my physics book and can't find the solution. First we have a drawing of a circle with mg and ft1 with two arrows pointing down at the top of the circle and at the bottom of the circle it has mg and ft2 with the ft2 arrow pointing up and the mg arrow pointing down. The question is: If its speed is 4.02 m/s and its mass is 0.291 kg, calculate the magnitude of the tension in the string when the ball is at the top of its path. If anyone could help me by just telling me how to figure out the magnitude of tension I'd be forever greatful, thanks.
