Question
Mass of $\mathrm{A}$ is(a) $\frac{\mathrm{m}}{2}$(b) $\frac{3}{4} \mathrm{~m}$(c) $\mathrm{m}$(d) $\frac{3}{2} \mathrm{~m}$
Step 1
Given that block A is moving with velocity $u$ and comes to rest after colliding with block B, we can say that the initial kinetic energy of the system is given by $\frac{1}{2} m_A u^2$. Show more…

Mass of $\mathrm{C}$ is (a) $\frac{\mathrm{m}}{2}$ (b) $\frac{3}{4} \mathrm{~m}$ (c) $\mathrm{m}$ (d) $\frac{3}{2} \mathrm{~m}$
The centre of mass of a system of two particles of masses $m_{1}$ and $m_{2}$ is at a distance $d_{1}$ from $m_{1}$ and at a distance $d_{2}$ from mass $m_{2}$ such that (a) $\frac{d_{1}}{d_{2}}=\frac{m_{2}}{m_{1}}$ (b) $\frac{d_{1}}{d_{2}}=\frac{m_{1}}{m_{2}}$ (c) $\frac{d_{1}}{d_{2}}=\frac{m_{1}}{m_{1}+m_{2}}$ (d) $\frac{d_{1}}{d_{2}}=\frac{m_{2}}{m_{1}+m_{2}}$
The mass of a body measured by a physical balance in a lift at rest is found to be $m$. If the lift is going up with an acceleration $a$, its mass will be measured as (a) $m\left(1-\frac{a}{g}\right)$ (b) $m\left(1+\frac{a}{g}\right)$ (c) $m$ (d) zero
