Current Question (ID: 19296)

Question:

$\text{A pendulum of length 2 m consists of a wooden bob of mass 50 g. A bullet of mass 75 g is fired towards the stationary bob with a speed } v. \text{ The bullet emerges out of the bob with a speed } \frac{v}{3} \text{ and the bob just completes the vertical circle. The value of } v \text{ is: (if } g = 10 \text{ m/s}^2)$

Options:

1. $10 \text{ ms}^{-1}$
2. $20 \text{ ms}^{-1}$
3. $30 \text{ ms}^{-1}$
4. $40 \text{ ms}^{-1}$

Solution:

$\text{Ans 10}$
