Applying the Law of Conservation of Momentum
Train car A is at rest when it is hit by train car B. The two cars, which have the same mass, are stuck together and
move off after the collision. How does the final velocity of train cars A and B after the collision compare to the initial
velocity of train car B before the collision?
The final velocity is double train car B's initial velocity
The final velocity is the same as train car B's initial velocity
The final velocity is half of train car B's initial velocity
The final velocity is zero since train car B will stop.

Standing side by side ,you and a friend step off a bridge at different times and fall for 1.6s to the water below.your friend goes first,and you follow after he has dropped a distance of 2.0m.when your friend hits the water,is the seperation between the two of you 2.0m or more than 2.0m? verify your answer with a calculation.

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
