Astar is rotating at 5.55x10-5 π rad/s, its velocity decelerates at a constant rate of 0.5x10-9 π rad/s2.?
what is the current rotational period of that star (in hours)?

what is the formula i should use to solve this equation. would it be the same as one of the rotational kinematics formula?

Explanation:

Given that,

Initial angular velocity of the star,

It decelerates, final angular speed,

Deceleration,

It is not required to use the rotational kinematics formula. The angular velocity in terms of time period is given by :

T is current rotational period of that star

T = 36036.03 second

or

1 hour = 3600 seconds

So, T = 10.01 hours

So, the current rotational period of that star is 10.01 hours. Hence, this is the required solution. Hence, this is the required solution.

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.
