Force = 0.20N .F = m ×a .& a = v/t then the f = m×v/t
The objects that look black are all tied for first place.
They lack a cell nucleus.
The combined system of you + elevator has two forces, a combined force of gravity and the tension in the cable. Consider the normal force acting on you from the elevator: N = mg if the elevator is at rest or moving at constant velocity. N = mg + ma if the elevator has an upward acceleration.
