Problem 47GP

A car with 58-cm-diameter tires accelerates uniformly from rest to 20 m/s in 10 s. How many times does each tire rotate?

Step-by-Step Solution:
Step 1 of 3

Solution Here we have to calculate the no of rotations of car tire in 10 seconds.to calculate that first we have note down the given data Given data: Initial speed of car v = 0 i Final speed of the car v = 20 m/s Time taken to increase speed is t = 10 s Radius of the car tire r = d/2 = 58 cm/2 = 0.29 m Initial angular speed of car is =0 rad/s The angular acceleration of car obtained by expression v = v0+at a = vv /t 0 a = v/t v0= 0 m/s The distance travelled by the car during the time it is accelerating calculated by the relation 2 2 2ax = v v 0 x = v v /2a = v /2a2 0 =v /2(v/t) =vt/2 Then the number of times rotate that is also called the no of circumferences of the tire is given by x = N(2r) N = x/d N = (vt/2)/d N = vt//2d N = (20 m/s)(10 s)/2((0.58m)/rotation) N = 55 rotations We can check our calculation by another way that is acceleration is constant,the distance car travels is just the average velocity times the car the time of travel.average velocity is given by x = v avgt = (v+v )0t = vt/2 55 is a reasonable number rotations for a car tire in 10 seconds
