T<span>he phenomenon of </span>static electricity<span> requires a separation of </span>positive<span> and </span>negative<span> charges. When two materials are in contact, electrons may move from one material to the other, which leaves an excess of </span>positive<span>charge on one material, and an equal </span>negative<span> charge on the other.</span>
i would sat C then the impact is weaker
X - Xo = 0.5(Vo +V)t
Xo cancels because it is 0 (she is at rest)
17 = 0.5(0+V)3.8
17 = 1.9V
Final velocity is 8.94737 m/s
Answer:
Hello There. ☆~\《--_^■^_--》\~☆ The final velocity of the car A is -1.053 m/s. For an elastic collision both the kinetic energy and the momentum of the system are conserved.
Hope It Helps!~ ♡

I would need an example or photo to give an answer.
