a cylinder and a hoop have the same mass and radius. they are released at the same time and roll down a ramp without slipping.?
1. The cylinder will reach the bottom first. Calculation of the acceleration Here the body acceleration should be rolled down the inclined surface . So the following equation should be used. a = gsinθ / (1 + k² / r²) Here. k is the radius of gyration. and r is the radius. Now . For hoop. k = r. a = gsinθ / (1 + r² / r²) = g / 2 x sinθ. 0.5 gsinθ. For cylinder
