Q14) A 1500 kg car moving on a flat, horizontal road negotiates a curve, as shown in Figure 12(a). If the radius
of the curve is 35 m and the coefficient of static friction between the tires and dry pavement is 0.5, find the
maximum speed the car can have and still make the turn successfully.
mg
Fig. 12: (a) The force of static friction directed toward the center of the curve keeps the car
moving in a circular path. (b) The free-body diagram for the car.

The package then travels 12 m along a horizontal surface where it pushes into a spring (k = 3000 N/m). The package compresses the spring a distance x before coming momentarily to rest. Then the package is pushed in the opposite direction by the spring. The coefficient of friction between the ramp/floor and the package is 0.21. Calculate x and determine if the package will stop before it gets back to the ramp or if it will begin to slide up the ramp. h 6) A roller blader (84 kg) is travelling at 19 m/s [E].

Built in 1983 in preparation for the 1984 Olympic Games, the 7-Eleven United States Olympic Training Center Velodrome features a 333.3-meter cement cycling track with semi-circular turns of radius 22m banked at 33 degrees. (HCPCRN31382)In 2016, Evelyn Stevens set a world record there going 47.98km in one hour. Assuming she traveled at a constant speed for the entire hour, was friction required for her to safely travel the turns on the track? If so, what minimum coefficient of static friction must be present? The mass of Evelyn and her bicycle combined was 62.8 kg.
