A car and a truck have the same linear momentum. Which one will have more speed and why?

Answer»

The truck and a car have the same momentum. 

i.e., p1 = MV where M is mass of truck and V velocity of the truck 

Similarly, p2 = mv where m is mass of the car, v is the velocity of the car Obviously mass of truck is greater than the mass of the car, so the speed of car will be more than truck in order to make p1 = p2
