In: A stopper on the end of a.5 meter string swings with a period of.25 seconds with a centripetal force of 2 Newtons. What is the mass of the stopper?

Objective: To develop our understanding of circular motion. Success criteria: be able to use circular motion to solve problems.

A dog sits 1.5 m from the center of a merry- go round and revolves at a tangential speed of 1.8 m/s. If the dogs mas is 18.5 kg, what is the magnitude of the centripetal force on the dog?

A 905 kg car travels around a circular track with a circumference of 3.25 km. If the magnitude of the centripetal force is 2140 N, what is the cars tangential speed?

Practice Problems:

Synthesis I own/ I dont understand An object with a mass of 1.5 kg makes a circle of radius 3 meters with a frequency of 2 Hz. How much work is done every revolution of the object?
