The upper point of a disk rolling on a horizontal surface has a linear velocity v1 = 10 m / s. Find the linear velocity v with which the disk axis moves.
To find the value of the speed of the axis of the specified disk, we will use the formula: Vо = V1 / 2 (the speed of points of the indicated disk relative to the horizontal surface is different; its upper point has an instantaneous speed 2 times the speed of the axis).
Variables: V1 – instantaneous linear velocity of the highest point of the specified disk (V1 = 10 m / s).
Calculation: Vo = V1 / 2 = 10/2 = 5 m / s.
Answer: The axis of the indicated disk moves at a speed of 5 m / s.
