Question

A rigid body is rolling without slipping on the horizontal surface,

Match the following;

A. Velocity at point i.e Va 1. v root2
B. Velocity at point i.e Vb 2. zero
C. Velocity at point i.e Vc 3. v
D. Velocity at point i.e Vd 4. 2v

​

Answer 1

Answer:

A. Velocity at point A i.e Va - 2. Zero

B. Velocity at the point B i.e Vb - 4. 2v

C. Velocity at the point C i.e Vc - 3. v

D. Velocity at the point D i.e Vd - 1. vroot2

Answer 2

When a body is rolling without slipping on a horizontal surface is defined by motion where the point of contact with the ground has zero velocity, so it matches the ground velocity and is not slipping. Therefore the answers are as follows

A )  Velocity at point A

⇒$V_{a}$ = Zero

B ) Velocity at the point B

⇒$V_{b}$ = 2V

C)  Velocity at the point C

⇒$V_{c}$ = 3V

D) Velocity at the point D

⇒  $V_{d}$ = v$\sqrt{2}$
