<p>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. The bullet emerges out of the bob with a speed&nbsp;<span class="equation">\(\frac{\upsilon}{3}\)</span>&nbsp;and the bob just completes the vertical circle. The value of v is ___________&nbsp;<span class="equation">\(ms^{-1}\)</span>. (if g = 10<span class="equation">\(m/s^2\)</span>)​​​​​​​</p>
