# Modiefied Atwood Machine Problemneed help.

1. A wheel is rotating about an axis perpendicular to the plane of the wheel and passing through the center of the wheel. The angular speed of the wheel is increasing at a constant rate. Point A is on the rim of the wheel and point B is midway between the rim and the center of the wheel. For each of the following quantities, it is the magnitude larger at A or at B, or is it the same at both points: a) angular speed, b) tangential speed, c) angular acceleration, d) tangential acceleration, and e) centripetal acceleration. Justify your answers.

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...
