A 3000 lbm car is moving initially at a speed of 20 ft/s south bound towards an intersection with a railroad track. When the car is 100 ft from the intersection, the driver sees a train traveling east bound toward the intersection at a speed of 15 ft/s. At the same same instant the train is 40 ft from the intersection. The train maintains a constant speed, and the driver has negligible reaction time. If the car is capable of...

A car of mass m 2000.0kg is moving at speed vi25.0 m/s towards East. A truck of mass m2 6000.0kg is moving at speed v2i-10.0m/s towards North. They collide at an m1- intersection and get entangled (complete inelastic collision). 1. What is the magnitude and direction of the final velocity of the entangled automobiles? 2. How much kinetic energy is lost in the collision. That is, calculate the change in the kinetic energy of the system
