- 7. A car is right on the verge of sliding as it speeds around a level circular track. The radius of the circular track is 21 m, and the coefficient of static friction between the car's tires and the track is 0.7, while the coefficient of kinetic friction is 0.56. What is the speed of the car?Rising fast ball. A batter in a baseball game will sometimes describe a pitch as being a rising ball, termed a hop. Although technically possible, such upward motion would require a large backspin on the ball so that an aerodynamic force would lift the ball. More likely, a rising ball is an illusion stemming from the batter's misjudgment of the ball's initial speed. The distance between the pitching rubber and home plate is 60.5 ft. If a ball is thrown horizontally with no spin, how far does it drop during its flight if the initial speed vo is (a) 36 m/s (slow, about 80 mi/h) and (b) 43 m/s (fast, about 95 mi/h)? (c) What is the difference in the two displacements? (d) If the batter anticipates the slow ball, will the swing be below the ball or above it?
