3) Two skaters (each has a mass of 50 kg) push off one another. They push with a force of 200N for 0.5 seconds. a) What is the velocity of each skater after the push?

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
