A wheel of radius 20 centimetres rolls along. How much would it move ahead after 10 rotations?

Open in App

Solution

Radius of the wheel = 20 cm

Distance covered by the wheel in one rotation = Perimeter of the wheel

= 2πr

= (2 × 3.141 × 20) cm

= 125.64 cm

∴ Distance covered by the wheel in 10 rotations = (125.64 × 10) cm = 1256.4 cm

Q. How much distance, in metres, a wheel of 25 cm radius will cover, if it rotates 350 times?

A uniform wheel of radius R is set into rotation about its axis at an angular speed $ω$ . This rotating wheel is now placed on a rough horizontal surface with its axis horizontal. Because of friction at the contact, the wheel accelerates forward and its rotation decelerates till the wheel starts pure rolling on the surface. Find the linear speed of the wheel after it starts pure rolling.
