A 10.0-g marble slides to the left at a speed of 0.400 m/s on the frictionless horizontal surface and has a head-on collision with a larger 30.0-g marble sliding to the right at a speed of 0.200 m/s.(a)If this collision is perfectly elastic, find the velocity of each marble after the collision.(b)Calculate the change in momentum of each marble. Compare the two values. Do your results make sense? Why?(c)Calculate the change in kinetic energy of each marble. Compare the two values. Do your results make sense? Why?
