Two cars are approaching a perpendicular intersection without a stop sign. Car 1 has a mass m₁ = 800 kg and is heading
north at V₁ 15 m/s. Car 2 has mass m2 = 700 kg and is heading west at an unknown speed v2. The two cars collide at the
intersection, and stick together as a result of the collision. The police report stated that after the collision, the two cars moved
together in a direction 40° west of north and stopped after sliding d 35 m from the collision point.
