58. Tire Rotation The P215/65RI5 Cobra Radial G/T tire has a diameter of exactly 26 inches Suppose that a car's wheel is making 2 revolutions per second (the car is trav- eling a little less than 5 miles per 17 hour). Then h(r) = 13 sin 4mt 21 + 13 represents the height h (in inches) of a point on the tire as a func- tion of time t (in seconds). The car starts to move when I= 0. (a) During the first second that the car is moving, at what time t is the point on the tire exactly 13 inches above the ground? (b) During the first second that the car is moving, at what time r is the point on the tire exactly 6.5 inches above the ground? (c) During the first second that the car is moving., at what time t is the point on the tire more than 13 inches above the ground?
