A rotating wheel requires 3.08-s to rotate through 37.0 revolutions. Its angular speed at the end of the 3.08-s interval is 97.4 rad/s. What is the constant angular acceleration of the wheel?

31.62

Explanation:

The angular velocity of the wheel at the end of the interval is 97.4 rad/s.

The time taken is 3.08 s.

Angular acceleration is given as:

where ω = angular velocity

t = time

Therefore, angular acceleration is:

a = 97.4 / 3.08

a = 31.62

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.
