Concept explainers
A truck has 2.5-ft tires (in diameter).
a. What distance will the truck travel with one rotation of the wheels? Give the exact distance and an approximation to the nearest tenth of a foot.
b. How far will the truck travel with 10,000 rotations of the wheels? Give the exact distance and an approximation to the nearest foot.
c. If the wheels turn at 672 rpm, what is the angular speed?
d. If the wheels turn at 672 rpm, what is the linear speed in feet per minute? Give the exact distance and an approximation to the nearest whole unit.
e. If the wheels turn at 672 rpm, what is the linear speed in miles per hour? Round to the nearest mile per hour. (Hint:
