A. A 1800 kg car's tires have a coefficient of friction equal to 0.25 on wet asphalt. What is the fastest that this car can drive along a flat turn with a radius of 200 m without slipping? B. How would this speed change if the car had a mass of 3600 kg instead? C. How would this speed change if the road were slanted? Would the possible speed be higher or lower?

A 1500 kg car moving on a flat, horizontal road negotiates a curve. If the radius of the curve is 1600 m and coefficient of static friction between the tires and the road (µ,) is 0.1, what is the maximum speed (in m/s) the car can have and still make the turn successfully. (g=10 m/s³) O a. 20 O b. 30 Oc. 10 O d. 40

Two balls, X and Y, are spun at a velocity of 6.5 m/s in a horizontal circle on the path shown below. Ball X has a mass of 1.3 kg, and ball Y has a mass of 0.81 kg. Which statement best describes the centripetal acceleration and centripetal forces on the balls? A. Both balls will experience equal centripetal force and centripetal acceleration. B. Ball X will experience greater centripetal force and greater centripetal acceleration. C. Ball Y will experience greater centripetal force, but ball X will experience greater centripetal acceleration. D. Both balls will experience the same centripetal acceleration, but ball X will experience greater centripetal force.
