A small object of uniform density rolls up a curved surface with an initial velocity ''. It reaches upto a maximum height of
with respect to the initial position. The object is:
Disc
Ring
Solid sphere
Hollow sphere
As we learned in concept
Rolling of a body on an inclined plane -
- wherein
K=Radius of gyration
= Angle of inclination
After solving
so object is disc.
Option 1)
Disc
This option is correct.
Option 2)
Ring
This option is incorrect.
Option 3)
Solid sphere
This option is incorrect.
Option 4)
Hollow sphere
This option is incorrect.
An object is dropped from a height h from the ground. Every time it hits the ground it looses 50% of its kinetic energy. The total distance covered as is : can you please solve this sorry but i really need a solution but iam not getting any ans
