On an icy road, a 1200-Kg car moving at 50 Km/h strikes a4400-Kg truck moving in the same direction at 35 Km/h. Thecombination is soon hit from behind by a 1500-Kg car speeding at 65Km/h. If all three vehicles stick together, what is the speed ofthe wreckage?

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

dang that balls went far
