defence exam Agniveer Vayu Group X & XY Mock Test 01/2026 Physics Rotational Motion Work and Rotational Kinetic Energy
A sphere of radius 'a' and mass 'm' along a horizontal plane with constant speed v0. It encounters an inclined plane at angle θ and climbs upward. Assuming that it rolls without slipping how far up the sphere will travel?
1
\(\frac{{v_0^2}}{{2g\,\sin \theta }}\)
2
\(\frac{{v_0^2}}{{5g\,\sin \theta }}\)
3
\(\frac{{7v_0^2}}{{10g\,\sin \theta }}\)
4
\(2 \over 5\) \(\frac{{v_0^2}}{{g\,\sin \theta }}\)
