and radius R? (MHTCET 2007)
3
5
(a)
mv (b) įmv? (c) my
(d) - my​

Answer 1

Answer:

a) mv

Explanation:

The total energy of a rolling ring of mass m and radius r is 3/2mv2 . since the ring is performing translation motion and also rotation motion ,the linear motion and rotation motion of a ring if we equate we get the answer as 3/2mv2

Answer 2

Answer:

the total enery of a rolling ring of mass m and radius r is 3/2 mv2. Since the ring is performing translation motion and also rotation motion, the linear momentum and rotation momentum of a ring if we equate we get the answer as 3/2 mv2.
