Consider your mass to be 60 kg for the purpose of this problem. a) You are on an elevator that is accelerating upvertically at 3.1 m/s2. What is the force that the elevatorexerts on your body? Is this force pointing up or down? If you were standing on a scale on the floor of the elevator, what weight would the scale indicate? b) Now consider that the elevator is accelerating downvertically at 3.1 m/s2.What is the force that the elevatorexerts on your body? Is this force pointing up or down? If you were standing on a scale on the floor of the elevator, what weight would the scale indicate? c) Now consider that the elevator is accelerating downvertically at 9.8 m/s2.What is the force that the elevator exerts on your body? Is this force pointing up or down? If you were standing on a scale on the floor of the elevator, what weight would the scale indicate?
