Question

A Yo-Yo is a toy in the form of a disc with a concentric shaft. A string is wound on the shaft. If it is suspended from the free end, then the string unwinds and winds so that the Yo-Yo falls down and rises up again and again. The ratio of the tension in the string while descending and ascending is

Q.
A yo-yo has mass m, inner radius r, and outer radius R. Its moment of inertia is I about its center. The yo-yo rolls without slipping on a horizontal table, and is pulled along by a horizontal string wound around its inner radius. The pulling by the string with tension T gives rise to an acceleration a. The yo-yo rolls without slipping.
What is the magnitude of acceleration a ?
Q. A yo-yo has mass m, inner radius r, and outer radius R. Its moment of inertia is I about its center. The yo-yo rolls without slipping on a horizontal table, and is pulled along by a horizontal string wound around its inner radius. The pulling by the string with tension T gives rise to an acceleration a. The yo-yo rolls without slipping. Find the force of friction f, in terms of tension T.
Q. A Yo-Yo of mass m has an axle of radius b and a spool of radius R. The Yo-Yo is placed upright on a table and string is pulled with a horizontal force →F to the right as shown in the figure.
The static friction coefficient between the Yo-Yo and the table is μs. Now there are two cases
Case (a): The string is pulled very gently.
Case (b): The string is pulled with a jerk.
The Yo- Yo will rotate
Q. A 0.1 kg yo-yo is initially hanging at rest at the end of its string. Then the tension force in the string is adjusted to 0.6N pulling upward.
Which one of the following describes how the yo-yo will move once the string's force is adjusted?
