A mass of 230 g, hanging on a spring, vertically oscillates with a period of 1 sec (the spring itself has no mass). After adding a mass, m, to the 230 g, we find that the period of oscillation of this mass-spring system becomes 2 sec. The value of m is equal to.

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
