gravitional force= mg, m is given
tension at top= mv^2/r-mg
tension at bottom mv^2/r+mg
A 570.0 g ball moves in a vertical circle on a 103.0 cm-long string. If the speed at the top is 4.30 m/s, then the speed at the bottom will be 10.65 m/s. (you'll learn how to show this Chapter 10.) What is the gravitational force (in N) acting on the ball?
What is the tension in the string(in N) when the ball is at the top?
What is the tension in the string(in N) when the ball is at the bottom?
