Question
A particle of mass $2 \mathrm{~kg}$ moving with a velocity $5 \hat{i} \mathrm{~m} / \mathrm{s}$ collides head-on with another particle of mass $3 \mathrm{~kg}$ moving with a velocity $-2 \hat{i} \mathrm{~m} / \mathrm{s} .$ \Lambdafter the collision the first particle has speed of $1.6 \mathrm{~m} / \mathrm{s}$ in negative $x$ direction. \Gammaind:(a) velocity of the cenure of mass after the collision(b) velocity of the sccond particle after the collision(c) coefficient of restitution
Step 1
Substituting the given values, we get: \[v_{cm} = \frac{2 \times 5 + 3 \times (-2)}{2 + 3} = 0.8 \hat{i} \, m/s\] Show more…

A particle of mass $m$, initially moving with speed $v$, collides head on elastically with an identical particle initially at rest. (a) Do you expect the total mass of the two particles after the collision to be (1) greater than $2 m$ (2) equal to $2 m,$ or (3) less than $2 m$ ? Why? (b) What are the total energy and momentum of the two particles after the collision, in terms of $m, v,$ and $c ?$
Two objects, one of mass 3 kg moving with a speed of 2 $\mathrm{m} / \mathrm{s}$ and the other of mass 5 $\mathrm{kg}$ and speed 2 $\mathrm{m} / \mathrm{s}$ , move toward each other and collide head-on. If the collision is perfectly inelastic, find the speed of the objects after the collision. (A) 0.25 $\mathrm{m} / \mathrm{s}$ (B) 0.5 $\mathrm{m} / \mathrm{s}$ (C) 0.75 $\mathrm{m} / \mathrm{s}$ (D) 1 $\mathrm{m} / \mathrm{s}$
