Suppose you have two identical bumper cars (we'll call them A & B). A moves towards B at 1.7 m/s. Meanwhile, B is moving towards A at -2.2 m/s (the negative sign indicates the opposite direction!). Both bumper cars have a mass of 600 kg. If the bumper cars collide and stick together, what is the final velocity of the two-car system after the collision? Assume they are traveling in a straight line.
You are coasting on your 10-kg bicycle at 15 m/s and a 8.0-g bug splatters on your helmet. The bug was initially moving at 4.0 m/s in the same direction as you. If your mass is 70 kg, (a) what is the initial momentum of you plus your bicycle? (b) What is the initial momentum of the bug? (c)What is your change in velocity due to the collision with the bug? (d) What would the change in velocity have been if the bug were traveling in the opposite direction?
