Question

If a rigid body rolls on a surface without slipping, then:

• A. linear speed is maximum at the highest point but minimum at the point of contact
• B. linear speed is minimum at highest point but maximum at the point of contact
• C. linear speed is same at all points of the rigid body
• D. angular speed is different at different points of a rigid body

Answer 1

The correct option is A linear speed is maximum at the highest point but minimum at the point of contact

As there is no slipping at B, thus $v=Rw$

$V_B=0$

$V_A=v+Rw=2v$

Velocity of any point P: $0\le V_P\le 2v$

Also angular velocity is same at different points of a rigid body.
