Constrained, uneven dumbbellClassical Mechanics Level 5
Calculate the velocity (in \(\displaystyle m/s\)) that should be given to the mass \(\displaystyle 2m\) (when the rod is in horizontal position) in counter-clockwise direction so that the rod just becomes vertical.
Details and Assumptions:
\(\bullet\) \(\displaystyle m = 250g\)
\(\bullet\) \(\displaystyle \ell = 25cm\)
\(\bullet\) \(\displaystyle g = 9.8 m/s^2\)
