Question

find the velocity vector of a particle moving with 10m/s in the direction if r vector =2icap-3jcap+4kcap​

Answer 1

Since, the collision is head on, the particle 1 will continue moving along the same line as before the collision, but there will be a change in the magnitude of it's velocity vector. <br> Let it starts moving with velocity

and particle 2 with

after collision, then from the conservation of momentum <br>

or,

(1) <br> And from the condition, given, <br>

<br> or,

(2) <br> From (1) and (2), <br>

<br> or,

<br> or,

<br> So,

<br>

<br> Positive sign gives the velocity of the 2nd particle which lies ahead. The negative sign is correct for

. <br> So,

will continue moving in the same direction. <br> Note that

if
