A pickup truck with mass 1800 kg is traveling eastbound at 15.0 m/s, while a compact car with mass 900 kg is traveling westbound at -15.0 m/s. The vehicles collide head-on, becoming entangled, i.e. perfectly inelastic collision. A. (1pt) Will momentum be conserved before and after the collision? If so, why? " B. (1pt) Will energy be conserved before and after the collision? If so, why? C. (1pt) Find the initial momentum for each vehicle before the collision. D. (1pt) Find the initial kinetic energy for each vehicle before the collision. E. (1pt) Find an expression for the final momentum of the entangled system after the collision in terms of vf. F. (1pt) Find the the final velocity v of the entangled system after the collision. G. (1pt) How much energy is lost, if any, in the collision
