The mass of the disc is M and the radius is R. The problem states:
A disc completes 44 revolutions as it slows from an angular speed of 1.5 rad/sec to a complete stop.
1)W/ acceleration constant, what times is required for it to come to rest?
2) what is the angular acceleration?
3)how much time is required to complete the first half of the 44 revolutions?
This was an in class problem to a intro level class @ college . the teach said we should know how to do this, does anyone know where to get started? I was absent on this day... :)
