Answer 2

Step-by-step explanation:

Given Two points, A and B, are on a disk that rotates about an axis, Point A is three times as far  from the axis as point B. If the speed of point  B is V, then the speed of point A is?  

• So A and B are points on a disk that rotates about an axis. Now point A is 3 times as far from the axis as point B.  
• So the speed of point B is v, we need to find the speed of point A.  
• On a rigid body all the points rotate at the same angular velocity ω. So we have v = ωR and the speed of a point is proportional to R.
• Angular speed is the rate at which an object changes its angle in radians
• Now the point is 3R and so the speed of point A will be 3v
