Apitcher exerts 100.0 n of force on a ball with a power output of 4,500 w. what is the velocity of the ball? 0.02 m/s, 45 m/s, 450 m/s, or 4500 m/s ? ? : / you!

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

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid
