A person of mass 50 kg stands on an accurate scale(that reads force in Newtons) in an elevator
A) Draw a free body diagram showing all of the forces acting on the person
B) What is the scale reading if the elevator is at rest
C) What is the scale reading if the elevator is moving upwards with a constant speed of 9.8 m/s.
D) What is the scale reading if the elevator is moving upwards with a speed of 3 m/s but is slowing down at
the rate 2.8 m/s2.
E) What is the scale reading if the elevator momentarily has zero velocity but is accelerating downwards at the rate of 9.8 m/s2?
