Name_____________________________________ General Science—Centripetal Acceleration Worksheet Page 1 1. What are the 3 ways that an object can accelerate? a. b. c. 2. If an object is travelling in a circle, in what direction is it accelerating? 3. A car goes around a bend at a speed of 35 mph. If the radius of curvature of the road is 150 ft, what is the centripetal acceleration experienced by the car? 4. If the car from #3 has a mass of 1300 kg, how much force is needed to produce the acceleration you calculated? 5. If a road has a radius of curvature of 220 ft, what is the maximum speed that can be travelled so that the acceleration is no more than 7 m/s2? 6. If the car from #5 has a mass of 1600 kg, how much force is needed to produce the given acceleration? Name_____________________________________ General Science—Centripetal Acceleration Worksheet Page 2 7. What type of force would be producing this acceleration? 8. What would be the coefficient of static friction that is necessary to produce this force? 9. You are designing a highway and want cars to be able to go around a bend at a speed of 65 mph and experience an acceleration of no more than 4.5 m/s2. What should the radius of curvature for the bend be?
