Explanation:
<em>a_c</em><em> </em><em>=</em><em> </em><em>v</em><em>_t</em><em>^</em><em>2</em><em>/</em><em>r</em>
<em>a_c</em><em> </em><em>=</em><em> </em>(0.5)^2/0.03
<em>a_c</em><em> </em><em>=</em><em> </em>8.33 m/s^2
The circumference of a circle is (pi) x (the diameter).
If the diameter of the wheel is 18 inches (1.5 feet), then its circumference is
(pi) x (1.5 feet) = 1.5π feet .
Every time the wheel rotates once, the car moves 1.5π feet.
1 mile = 5,280 feet
In order for the car to move 5,280 feet, the wheel has to rotate
(5,280 / 1.5π) times.
(5,280 / 1.5π) = 1,120.4508 times
Rounded to the nearest whole number: <em>1,120 revolutions</em>
