STRATEGY The total momentum of the vehicles before the collision, Pi, equals the total momentum of the vehicles after the collision, pf, if we ignore friction and assume the two vehicles form an isolated system. (This is called the "impulse approximation.") Solve the momentum conservation equation for the final velocity of the entangled vehicles. Once the velocities are in hand, the other parts can be solved by substitution. SOLUTION (A) Find the final speed after collision. Let m₁ and V₁¡ represent the mass and initial velocity of the pickup truck, while m₂ and V₂¡ pertain to the compact. Apply conservation of momentum.
