Aparticle of mass, m = 3.0kg movers with a uniform velocity, v = (5m/s)i +(3m/s)j. at the time, t, the particle passes through the point r = (2m)i - (3m)j from the origin. calculate the magnitude and direction of the angular momentum about the origin at time t. (angular momentum is given by l= mv x r

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
