Two sumo wrestlers run towards each other, the first has a mass of 169 kg and is running at 14 m/s. The second wrestler has a mass of 302 kg and is running with a speed of 18
m/s. They collide in an elastic collision. If the 302 kg wrestler bounces backwards at 4 m/s, find the final velocity of the first wrestler.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
