Abus and a car have an inelastic head-on collision. the bus has a mass of 1.5 × 103 kilograms and an initial velocity of 20 meters/second. the car has a mass of 9.5 × 102 kilograms and an initial velocity of -26 meters/second. what is their total momentum after the collision?

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question

What is a good example of instantaneous speed

Me pl give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.
