JEE Main 1 February 2024, Shift 2, Physics Q35

Question 35 of 90 in this shift, Physics question 5 of 30, Section A.

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 :

The figure, in words

A disc (seen end-on, marked with a dot) rolls to the right with speed v along a horizontal surface and then up an inclined plane; at the top position the disc is shown at height h above the horizontal dotted line.

(1) $\frac{v^2}{g}$
