A disc of radius $R$ and mass $M$ is rolling horizontally without slipping with speed $v$ . It then moves up an inclined smooth surface as shown in figure. The maximum height that the disc can go up the incline is:

Options:

Answer:

Solution:

Only the translational kinetic energy of disc changes into gravitational potential energy and rotational $KE$ remains unchanged as there is no friction.

$\frac{1}{2} m v^{2} = m g h$

$\Rightarrow h = \frac{v^{2}}{2 g}$
