Question
1.a A hoop rolls with constant velocity and without sliding alonglevel ground. Its rotational kinetic energy is: the same as itstranslational kinetic energyfour times itstranslational kinetic energy
half itstranslational kinetic energy
twice itstranslational kinetic energy
one-third itstranslational kinetic energy 1b. Two uniform cylinders have different masses and differentrotational inertias. They simultaneously start from rest at the topof an inclined plane and roll without sliding down the plane. Thecylinder that gets to the bottom first is: neither (theyarrive together)
the one with thelarger mass
the one with thelarger rotational inertia
the one with thesmaller rotational inertia
the one with thesmaller mass Pls try to explain ur answers. I'll rate immediately. Thanks!
Explanation / Answer
1.a A hoop rolls with constant velocity and without sliding alonglevel ground. Its rotational kinetic energy is: the same as itstranslational kinetic energy four times itstranslational kinetic energy half itstranslational kinetic energy twice itstranslational kinetic energy one-third itstranslational kinetic energy option 1 is correct[. ie the same as its translationalkinetic energy] 1b. Two uniform cylinders have different masses and differentrotational inertia. They simultaneously start from rest at the topof an inclined plane and roll without sliding down the plane. Thecylinder that gets to the bottom first is: neither (theyarrive together) the one with thelarger mass the one with thelarger rotational inertia the one with thesmaller rotational inertia the one with thesmaller mass option 1 is correct.[ ie neither (they arrive together)]
