Question

A disc is performing pure rolling on a smooth stationary surface with constant angular velocity as shown in the figure. At any instant, for the lowermost point of the disc., Velocity is v , acceleration is zero, Velocity is zero, acceleration is zero, Velocty is v , acceleration is v 2 R, Velocity is zero, acceleration is nonzero

From figure V n e t f o r l o w e s t p o i n t = v - R ω = v - v = 0 and A c c e l e r a t i o n = v 2 R + O = v 2 R (Since linear speed is constant) Hence (D)
