At what speed would a 1140kg car have the same momentum as a 12,600kg truck traveling at 25 km/hr?
The hint given to this problem is that I need to find the velocity of the car and truck.
Converting 25 km/hr to m/s I get 6.944 m/s as the initial velocity.. The professor told us that the velocity should be 15 for the truck. How is the professor getting this number???

Your conversion is correct.
The Prof errs.
