A ball with a mass of 1.50 kg is attached to the end of a string that is 0.400 m in length. You swing the ball so that it swings in a vertical circle, traveling at a speed of 4.80 m/s at the top of the circle. (a) Draw the free-body diagram of the ball. Make sure you label all your vectors and clearly indicate their direction. (b) What is the tension in the string when the ball is at the topmost point of the circle?

Answer #1
Concept - use Newton’s law of motion for the
motion of the ball at the top of the circle to find the required
value of tension as shown below

1. For a stationary ball of mass m = 0.200 kg hanging from a
massless string, draw arrows (click on the “Shapes” tab) showing
the forces acting on the ball (lengths can be arbitrary, but get
the relative lengths of each force roughly correct). For this case
of zero acceleration, use Newton’s 2nd law to find the
magnitude of the tension force in the string, in units of Newtons.
