Question

14. Two solid balls (one larger, the other small) and a cylinder roll down a hill. Which has the greatest speed at the bottom and which the least? the larger ball has the greatest, the small ball has the least. b. the small ball has the greatest, the larger ball has the least. the cylinder has the greatest, the small ball has the least. d. both balls have the same greater speed, the cylinder has the least.​

Answer 1

Answer:

1 option is correct bro

Explanation:

i think that OK?

Answer 2

Answer:

D

Explanation:

The radius of gyration (K) of the Cylinder is more than the that of Sphere Balls so More the K less will be the speed. K of cylinder>K of sphere

Then, speed of the Balls is greater than the cylinder But in Rolling Motion, V=

$v = \sqrt{2gh} \frac{1}{1 + \frac{ {k}^{2} }{ {r}^{2} } }$

Speed does not depend upon of mass So both balls have same speed so option d is correct
