Two railway cars are on a straight railroad track. The first,
with mass 8000 kg, moves slowly at a velocity of 0.05 m/s to the
right in the direction of the second car of mass 15000 kg, which is
stationary.
(a) What is the total momentum (relative to the ground) of both
cars together?
kg m/s
They collide and stick to each other. What is the total momentum right after the collision? For the short times involved, you can take the tracks to be frictionless.
kg m/s
What is the final velocity of both railway cars?
m/s
