Ahoop of mass and radius and a solid cylinder of mass and radius are rolling along level ground with the same translational speed. which object has the greater total kinetic energy?

the kinetic energy of hoop will be more than kinetic energy of solid cylinder

Explanation:

kinetic energy of rolling is given as

here we know that for pure rolling we have

now we also know that

here k = radius of gyration

now we have

now we know that for

hoop

for Solid cylinder

now the kinetic energy of hoop will be more than kinetic energy of solid cylinder

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6

iron would move it is magnetic there is a mag field around the current in the wire
