Question

Two objects each mass 1.5kg moving in the same straight line opposite direction.The velocity of each object is 2.5m/s before the collision during which they are stick together .What will be the velocity of the combined after collision?

Answer 1

Since there is not any change in momentum the momentum will remain conserved

M1u1 +m2u2 = MV
1.5× 2.5 + 1.5×(-2.5)= (1.5+1.5)V
V = 0

So they will not move
