Students in question are in the back of a 3200 kg moving truck travelling east at 50 km/h. The students intend on ramming the truck with their 2000 kg vehicle to force it to a stop. As the moving truck moves through a nice open parking lot, they travel at 80 km/h directly southwest (50 degrees south of west) and collide with the moving truck. Both vehicles become stuck together and move off as one after the collision. Treat east...
