PhysicsEasysingle choice

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.

Options:

Answer:

Solution:

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 $A c c e l e r a t i o n = \frac{v^{2}}{R} + O = \frac{v^{2}}{R}$

(Since linear speed is constant)

Hence (D)
