A) 6.25rad/sec
B) 0.625 rad/sec
C) 3.35 rad/sec
D) 0.335 rad/sec
Correct Answer: B
Solution :
[b] \[Let\text{ }x=\]distance between hinge and centre of the door \[=L/2=\frac{1}{2}=0.5m\] As per conservation of angular momentum \[mvx=I\omega \] \[\Rightarrow w=\frac{mvx}{I}=\frac{0.01\times 500\times 0.5}{\frac{1}{3}\times 12\times {{(1)}^{2}}}=0.625rad/s\]You need to login to perform this action.
