Question 621: Centre of Mass and Rotational Motion

Question

A wheel of a bullock cart is rolling on a level road as shown in the figure below. If its linear speed is $$v$$ in the direction shown, which one of the following options is correct ($$P$$ and $$Q$$ are any highest and lowest points on the wheel, respectively)?

Accepted Answer

In the case of pure rolling,
The topmost point will have velocity $$2 v$$ while point $$Q$$ i.e. lowest point will have zero velocity. Hence point $$P$$ moves faster than point $$Q$$.

Answer

Point $$P$$ moves slower than point $$Q$$

Answer

Point $$P$$ moves faster than point $$Q$$

Answer

Both the points $$P$$ and $$Q$$ move with equal speed

Answer

Point $$P$$ has zero speed
