1. What is the radius of a circle with circumference 24m? 2. If a circle has a diameter of 14m what is the circumference? 3. If a car goes around a circular track 200 times in an hour what are the period and frequency? 4. A car goes around a circular track of 2 km radius with a speed of 40kph. What is the acceleration experience by the car? Which way is the acceleration pointing? s. If the car in Q1 has a mass of 1,500 kg what is the , needed to keep the car on the track? 6. If the diameter of the tires on the car above are 0.8m, how many rotations do they make in rotation around the track? What their rotational velocity, period and frequency? 7. Assume a mass of 1kg being swung around a circle on a 1m string at a rate of 60 rotations per minute at a height of 2m off the ground. What is its linear velocity (Speed)? If the string breaks, how far from the center of rotation would the mass land?
