Question

A small 200 kg sports car collides with a large 800 kg truck. Before the collision, the sports car was traveling at 25 m/s and the large truck was traveling at 10 m/s in the same direction. What was the total momentum of the car and truck?. In the collision if the car and truck stick together, what will be their speed after the collision?

Answer 1

Step-by-step explanation:

psystem = m1v1 + m2v2

¡ The total momentum of the system before the collision equals

the total momentum of the system after the collision. Thus,

psystem = p’system
