Let the average diameter of the automobile tire is about 2 feet. Therefore its circumference is .
Now we have to convert an automobile tire is rated to last for 60,000 miles in to feet.
As .
So,
Thus the number of revolutions,
Hence, order of magnitude of revolutions is 7.
Answer:
0.69s
Explanation:
10 cm = 0.1 m
Let t be the time that radial and tangential components of the linear acceleration of a point on the rim be equal in magnitude. At that time we have the angular velocity would be
And so the radial acceleration is
The tangential acceleration is always the same since angular acceleration is constant:
For these 2 quantities to be the same
