Will rate lifesaver to whoever can explain best indetail how to solve the problem. Thank you! The tires on a new compact car have a diameter of 2.0 ft andare warranted for 64,000 miles. (a) Determine the angle (in radians) throughwhich one of these tires will rotate during the warrantyperiod.
1 rad
(b) How many revolutions of the tire are equivalent to your answerin (a)?

1 rad
(b) How many revolutions of the tire are equivalent to your answerin (a)?
2 rev

Explanation / Answer

Diameter of the tire d = 2 ft = 2 * 0.304 m = 0.608 m

Circumference of the tire S = (pi) d = 1.91 m

Warrenty distance S ‘ = 64000 miles= 64000 * 1609m

So, No.of revolutions in warenty period N = S ‘/ S

                                                                       = 53.91 * 10 ^ 6 rev

(a). required angle   = N * 2(pi) rad

                                = 338.73 * 10 ^ 6 rad

(b). No.of revlutions = 53.91 * 10 ^ 6 rev
