Question 4 (10 points) 1. A 1002 kg compact car is driven by a brain dead biology teacher at 10.0 m/s [N]. A knowledgeable physics student sees the compact car and attempts to take the car out in the name of science. The student drives a 2002 kg car at 8.00 m/s [W]. They collide and stick together. The bio teacher is saved for future experimentation, the physics student was unharmed. (Do not attempt this at home; professional drivers used for simulation). a. Determine the initial velocity of the two joined cars immediately after the collision. (5) b. Determine whether the collision is elastic or inelastic through kinetic energy calculations. Discuss
