### Uniform Circular Motion Presentation Free Response #01

A 0.45 kg ball is attached to the end of a string. It is swung in a vertical circle of radius 0.750 m. At the top of the circle its velocity is 3.2 m/s.a. Draw a free body diagram for the ball when it is at the top of the circle. Next to that diagram indicate the direction of its acceleration.b. Use that free body diagram to set up the equations needed to determine the Tension in the string.c. Solve those equations for the Tension in the string.These videos are part of a unit of instruction created by NJCTL. Students and teachers can find additional free instruction on this topic at the site listed below. This includes the full unit presentation, homework with solutions, and assessments (teachers only).Uniform Circular Motion Presentation - http://njctl.org/courses/science/algebra-based-physics/uniform-circular-motion/uniform-circular-motion-presentation-2/
