Task id13243
A hoop of radius R rolls without sliding along a horizontal plane with angular velocity w (figure). Its movement can be considered as rotation around the instantaneous axis A. Is it true that the acceleration of point B is equal to w2x and directed to point A (x is the distance between points A and B)? Derive a formula for the acceleration of point B, considering its motion as rotation around the instantaneous axis A.
