1.
A body of mass $5 \,m$ initially at rest explodes into $3$ fragments with mass ratio $3 : 1 : 1$. Two of fragments each of mass $'m'$ are found to move with a speed of $60 \,m/s$ is mutually perpendicular directions. The velocity of third fragment is- $ 10\sqrt{2}$
- $ 20\sqrt{2}$
- $ 20\sqrt{3}$
- $ 60\sqrt{2}$
2.
A particle of mass $4 \,m$ explodes into three pieces of masses $m, m$ and $2 \,m$. The equal masses move along $X$-axis and $Y$-axis with velocities $4\, ms ^{-1}$ and $6\, ms ^{-1}$ respectively. The magnitude of the velocity of the heavier mass is- $\sqrt{17}\, ms^{-1}$
- $ 2 \sqrt{13}\,ms^{-1}$
- $ \sqrt{13}\,ms^{-1}$
- $ \frac{ \sqrt{13}}{2} \,ms^{-1}$
3.
A body of mass $2 \,kg$ moving with velocity of $6\, m/s $ strikes in elastically with another body of same mass mass at rest. The amount of heat evolved during collision is- 18 J
- 36 J
- 9 J
- 3 J
4.
A mass of $0.5\, kg$ moving with a speed of $1.5\, m/ s$ on a horizontal smooth surface, collides with a nearly weightless spring of force constant $k = 50\, N/m$. The maximum compression of the spring would be- $0.5\,m$
- $0.15\,m$
- $0.12\,m$
- $1.5\,m$
