A uniform hollow sphere of mass 200 g rolls without slipping on a plane horizontal surface with its centre moving at a speed of 5.00 cm/s. Its kinetic energy is:

A

`4.17xx10^(-4)J`

B

`8.72xx10^(-3)J`

C

`6.25xx10^(-4)J`

D

`3.61xx10^(-4)J`

Text Solution

Verified by Experts

The correct Answer is:
A
m= 0.2 kg, v= 5 cm/s
KE in rolling `=1/2 mv^2 + 1/2 I omega^2`
`=1/2mv^2 (1+ K^2/R^2) = 4.17 xx 10^(-4) J`
