Homework Statement



A heavy ball with a weight of 130 is hung from the ceiling of a lecture hall on a 4.6--long rope. The ball is pulled to one side and released to swing as a pendulum, reaching a speed of 5.6 as it passes through the lowest point.

What is the tension in the rope?

Hi racer98jc, welcome to PF.

What are the forces acting on the ball at the lowest point of the swing?

Hello,

at the bottom: tension and the balls own weight are acting on it. Correct?

Correct(the question probably wants you to ignore frictional forces)
