Question: A heavy ball with a weight of 150N is hung from the ceiling of a lecture hall on a 4.8-m-long rope. The ball is pulled to one side and released to swing as a pendulum, reaching a speed of 5.9m/s as it passes through the lowest point.
Question 1: What is the tension in the rope at that point?
I want help to calculate the tension in the rope at that point.
