Question

Principle of conservation of linear momentum
The figure shows a particle A of mass,m moving with a velocity,u toward a, colliding elastically,A and B move off with velocities, v and V respctively as shown.
(i) Write the equation that summarise the conservation of linear momentum and energy during the collision.
(ii) From these two equation,it can be deduce that v=V-u.
Using this result,find the fractional loss of kinetic energy of A in terms of m and M only.

Answer 5

Ok so you're just looking for the second part or the first part? What specifically are you having trouble with?

Answer 6

2nd part

Answer 7

Only particle A is moving before the collision correct?

Answer 8
