2. Homework Equations

(tangential speed) v= rw

(angular speed) w=v/r or 2π/t

(tangential acceleration) = r * (change in w/ change in t)

(angular accel.) =change in w/ change in t

## The Attempt at a Solution

I know that the further a point is from the center, the faster its velocity.

the closer a point is to the center, the slower its velocity.

Therefore, the magnitude will always be greater at point A?????

I think Point a = r(radius) and point B= 1/2r.....

I dont know how to approach the problem...
