A ball is thrown upward with an initial velocity of 13 m/s. Using the approximate value of g = 10 m/s2, what are the magnitude and direction of the velocity: (a) 1 second after it is

thrown? (b) 2 seconds after it is thrown?

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
