  1. A B 60cm A tire with a diameter of 60 centimeters turns at a rate of 100rpm. What is the linear speed of the car? Compare the linear and angular speeds of a point A and B.(<,>, =) vA _______vBωA ________ωB

  2. A 180 gram rubber stopper is tied to a string and swung in a vertical circle of radius 1.2 meters. What is the minimum speed the mass needs at the top in order to successfully complete the circle? What would the tension in the string be if the stopper had the same speed at the bottom of the circle?

  3. 8m 5kg 2.5m 1.5m 8kg ? The following system is in equilibrium (balanced). What is the unknown mass?

  4. A car rounds a circular curve of radius 40 meters. The coefficient of friction between the road and the tires is 0.8. What is the maximum speed the car can have and still successfully negotiate the curve? 40m

  5. The gravitational force between two mass is 20N. What would the force be if the distance between the masses was cut in half? 20N 20N r

  6. r = 1.5 x 107 m A 500kg satellite has an orbital radius of 1.5 x 107 meters. Calculate the linear velocity and the period of the satellite. Mass of the earth = 6.0 x 1024 kg
