Questions
Two identical solid cylinders roll from rest on two identical inclined planes of slant lengths s and 2s but of the same height h. Then, the velocities, and acquired by the cylinders when they reach the bottom of the incline are related as
detailed solution
Correct option is A
For pure rolling , kinetic energy of a solid cylinder = 12mv2+12(12mR2) = 34mv2conserving energy , 34mv2 =mgh ⇒v =43gh therefore,v1=v2Talk to our academic expert!
