355303 A sphere of mass \(m\), moving with velocity \(V\), enters a hanging bag of sand and stops. If the mass of the bag is \(M\) and it is raised by height \(h\), then the velocity of the sphere was -

1 \(\dfrac{M+m}{m} \sqrt{2 g h}\)
2 \(\frac{M}{m}\sqrt {2gh} \)
3 \(\dfrac{m}{M+m} \sqrt{2 g h}\)
4 \(\frac{m}{M}\sqrt {2gh} \)

355304 A particle of mass \(m\) moving with velocity \(v\) strikes a stationary particle of mass \(2 m\) and sticks to it. The speed of the system will be

1 \(2 v\)
2 \(v / 2\)
3 \(3 v\)
4 \(v / 3\)

355305 A block of mass \(m\) rests on a rough horizontal surface (Coefficient of friction is \(\mu\) ). When a bullet of mass \(m\)/2 strikes horizontally, and get embedded in it, the block moves a distance d before coming to rest. The initial velocity of the bullet is \(k \sqrt{2 \mu g d}\), then the value of \(k\) is
