Truck moves with a velocity of 43 m\s and collides with the stationary car with exactly 1 / 5 of its mass. If the two vehicles are locked together, calculate the magnitude of the velocity of their combined masses immediately after the collision?
1/5 = 0.2
original momentum = m *43
final momentum = 1.2 m * v
no momentum is lost in this transaction
1.2 v = 43
v = 43 / 1.2
