Mr. M is floating in space. He turn to find Mrs. M also floating is space. They face each other. As you may have guessed, Mr. M then pushes on Mrs. M, and the both travel in opposite directions. What will the sum of their momentums be after the push AND why?

please answer the second one

The engine of an unpowered toy train is rolling at a constant speed on a level track, as shown in Fig. 3.1. The engine collides with a stationary toy truck, and joins with it. 3 moving engine stationary truck track Fig. 3.1 Before the collision, the toy engine is travelling at 0.32 m/s. The mass of the engine is 0.50 kg. (a) Calculate the momentum of the toy engine before the collision. (b) The mass of the truck is 0.30 kg. Using the principle of conservation of momentum, calculate the speed of the joined engine and truck immediately after the collision.

Physics homework assignment, I don't know how to do this question. There's three parts but it's all one question. Thanks for the help!

4. You need to show your work in detail to get any credit. Before collision: The red car (on the left) has the velocity of 10.0 m/s and mass of 4.8 kg. The blue car (on the right) has the velocity of -5.6 m/s and mass of 4.4 kg. After elastic collision: The blue car moves with the velocity of 8.8 m/s. (a) What is the initial momentum of the red car? (b) What is the initial momentum of the blue car? (c) What is the total momentum of the system of blue and red car before collision? (d) What is the final momentum of the blue car? (e) What is the impulse on the blue car (in kg.m/s)? (f) Is the system consisting of the blue and red car an isolated system? (g) What is the impulse on the red car (in kg.m/s)? (h) What is the velocity of the red car after the collision? (i) Draw annotated p-t and F-t graphs for both carts at all stages of collision. Assume that collision occurred for 0.5 seconds.
