Question
An object is traveling in the positive $x$ direction with speed $v$. A second object that has half the mass of the first is traveling in the opposite direction with the same speed. The two experience a completely inelastic collision. The final $x$ component of the velocity isA. 0B. $\mathrm{v} / 2^{v / 2}$C. $\mathrm{v} / 3^{v / 3}$D. $2 \mathrm{v} / 3^{2 v / 3}$E. $v$
Step 1
The first object has mass $m$ and is moving in the positive $x$ direction with speed $v$. The second object has half the mass of the first, i.e., $m/2$, and is moving in the opposite direction with the same speed $v$. Show more…

A particle of mass ' $m^{\prime}$ moving with velocity ' $v^{\prime}$ collides inelastically with a stationary particle of mass ' $2 \mathrm{~m}^{\prime}$. The speed of the system after collision will be (a) $\frac{v}{2}$ (b) $2 v$ (c) $\frac{v}{3}$ (d) $3 v$
A ball of mass $m$ moving with velocity $V$, makes a head on elastic collision with a ball of the same mass moving with velocity $2 V$ towards it. Taking direction of $V$ as positive velocities of the two balls after collision are (a) $-V$ and $2 V$ (b) $2 V$ and $-V$ (c) $V$ and $-2 V$ (d) $-2 V$ and $V$
In a perfectly inelastic one-dimensional collision between two moving objects, what condition alone is necessary so that the final kinetic energy of the system is zero after the collision? a. The objects must have initial momenta with the same magnitude but opposite directions b. The objects must have the same mass c. The objects must have the same initial velocity d. The objects must have the same initial speed, with velocity vectors in opposite directions.
