Questions
A solid cylinder rolls up an inclined plane of inclination with an initial velocity v. How far does the cylinder go up the plane?
detailed solution
Correct option is D
Let the cylinder go up the plane upto a height h. Let M and R be the mass and radius of cylinder respectively. According to law of conservation of mechanical energy, we get 12Mv2+12Iω2 = Mgh (∵ For a solid cylinder, I = 12MR2) 12Mv2+14MR2ω2 = Mgh 12Mv2+14Mv2 = Mgh (∵ v = Rω) 34Mv2 = Mgh h = 3v24gLet s be distance travelled by the cylinder up the plane. s=hSin θ=3v24gSin θTalk to our academic expert!
