The two block in (Figure 1) are at rest on frictionless surfaces. What must be the mass of the right block in order that the two blocks remain stationary? Suppose that m = 10 kg .

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
