Question
Two trucks moving towards each other collide head-on. Truck A has a mass of 8000kg and is moving to the right with a speed of 10 m/s while truck B has a mass of 6000kg and a velocity of 5 m/s and is moving to the left.
What is the velocity of the vehicles after they collide?

Explanation
The equation of conservation of momentum is;
Initial momentum before collision = final momentum after collision
M1V1 + M2V2 = V (M1+M2)
(8000 X 10) + (6000 X -5) = V (8000+ 6000)
80, 000 + -30, 000 =14,000V
50,000/14000=V
3.57 km/s
