Your 64-cm-diameter car tire is rotating at 3.3 rev/swhen suddenly you press down hard on the accelerator. after traveling 250 m, the tire's rotation has increased to 6.4 rev/s. what was the tire's angular acceleration? give your answer in rad/s^2.

Explanation:

The given data is as follows.

   Initial velocity, u =

                           = 20.724 rad/sec

   Final velocity, v =    

                           = 40.192 rad/sec

Now, we will calculate the value of angular rotation (d) as follows.

          d = No. of revolutions ×

         d =

            =

            = 781.25 rad

Also, we know that,

or,              a =

                      =

                      =

                     = 0.7589

Thus, we can conclude that the tire's angular acceleration is 0.7589 .

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
