a group of students are performing an experiment in class using collision carts on a track. A 5.0 kg cart moving to the right at 4.0 m/s hits a 7.0 kg cart moving to the left at 6.0 m/s. immediately after the collision, the 7.0 kg cart moves to the right at 3.0 m/s. what is the velocity of the 5.0 kg cart after the collision?

answer:     true

step-by-step explanation:

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128
