two carts with identical masses of 500 gram and 400 gram collide on an experimental linear track. the first cart has a velocity of 2 cm/s, while the second has a velocity of -4 cm/s.
a- draw the diagram of the given problem showing positions of car before and after collision in a perfectly inelastic collision.
b- formulate the equations needed in solving for the final velocities of the car in a perfectly elastic collision.
c- solve for the final velocities of the car in a perfectly elastic collision and analyze which of the answers is physically possible.
