A 2,950 kg truck jumps the median and clobbers a 660 kg station wagon in a head-on collision. You are tasked with determining the truck’s initial speed for insurance purposes. An observer states that the station wagon was traveling at a speed of 32.5 m/s and that after the collision, the two vehicles stuck together and were moving at a speed of 22.7 m/s in the direction the truck was originally moving. What was the truck’s original speed?
