Work Energy And Power Question 254
Question: Two objects each of mass m are connected with a uniform rope having same mass m and length $ \ell =10/3 $ m are shown in the figure. The rope can slide on a frictionless pulley which is fixed to the edge of the table. Initially 1/3 of the rope hangs vertically. Friction is negligible everywhere. If the system is released from rest and object on the right hand side descend further by a distance of 1/3, what would be the speed of the object (in m/s)?
Options:
A) 2.12 m/s
B) 3.33 m/s
C) 0.33 m/s
D) 4.12 m/s
Show Answer
Answer:
Correct Answer: B
Solution:
[b] initial Final By using mechanical energy conservation $ v=\frac{10}{3}=3.33m/s $
