A wheel is spinning with an initial speed of 50 rad/s. It’s diameter is 4 m and it comes to a stop after 5s.

  1. Find the angular acceleration

  2. Find the radians

  3. Find how many times it made a full spin

If the explanation could be as step-by-step as possible as I really do not understand this concept that would be great thank you!

  1. Find how far it went
