1. The problem statement, all variables and given/known data A 60 kg person is standing in an elevator. Calculate each one of the forces acting on the person while the elevator is: a) at rest, b) moving up with a constant velocity of 3m/s, c) accelerating down at 4m/s^2, d) accelerating up at 4m/s^2. 2. Relevant equations Force = mass times acceleration. im not exactly sure what "each one" is supposed to imply, i just know that for the first one, the net force is zero. i also know that the normal force is equal to the weight of an object, W= mg, when the object is in equilibrium. 3. The attempt at a solution im not sure what formulas/figures to use in order to show each one of the forces for each situtation. should i write F= 0 for the forces in the first example? such as: F_normal = 0, for the force of the elevator down, F_g = 0 for the force of gravity, and then F_net = 0 for the net force?
