Question
A block of mass $2 \mathrm{~m}$ moving with constant velocity $3 \vec{v}$ collides with another block of mass $m$ which is at rest and stick to it. The velocity of the compound block after the collision is(a) $\vec{v}$(b) $3 \vec{v} / 2$(c) $2 \vec{v}$(d) $3 \vec{v}$
Step 1
We have two blocks: one with mass \(2m\) moving with velocity \(3\vec{v}\) and another block with mass \(m\) at rest. After the collision, the two blocks stick together. Show more…

Round 1
A body of mass $2 \mathrm{~kg}$ moving with a velocity of $3 \mathrm{~m} / \mathrm{s}$ collides head-on with a body of mass $1 \mathrm{~kg}$ moving in opposite direction with a velocity of $4 \mathrm{~m} / \mathrm{s}$. After collision two bodies stick together and moves with a common velocity which in $\mathrm{m} / \mathrm{s}$ is equal to (a) $\frac{1}{4}$ (b) $\frac{1}{3}$ (c) $\frac{2}{3}$ (d) $\frac{3}{4}$
A body of mass $1 \mathrm{~kg}$ moving along a straight line with a velocity of $4 \mathrm{~m} \mathrm{~s}^{-1}$, collides head on with a body of mass $2 \mathrm{~kg}$ moving along the same line with a velocity of $3 \mathrm{~m} \mathrm{~s}^{-1}$. After collision the two bodies stick together and move with a common velocity of magnitude $\left(\mathrm{m} \mathrm{s}^{-1}\right)$ (a) $\frac{3}{2}$ (b) $\frac{10}{3}$ (c) $\frac{2}{3}$ (d) $\frac{3}{4}$
