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 .

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
