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 vv. 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.
