A 51 kg person standing on a scale in an elevator that is accelerating upwards at 2m/s2. What is the normal force acting on the person (i.e., what would the scale read)?
FN = ?
Net Force = mass x ( Net acceleration )
Here net acceleration is sum of acceleration due to gravity and the lift acceleration.
Net acceleration= 9.8m/s2 + 2m/s2 =11.8 m/s2
Net force = 51 x 11.8 N = 601.8 N

if a person was standing on a scale in an elevator that is accelerating down with 1 m/s2 the reading on the scale is 4.5kg DURIN THE DECELERATION OF THE ELEVETOR What is the normal force? and what is the mass of the person, thanks
A person has a mass of 90kg. He is standing on a scale in an elevator. The elevator is accelerating upward at 5/3 m/s2. What does the scale read on the earth and moon in kg?
Draw a free-body diagram for a 70-kg person standing in an elevator carrying a 15-kg backpack (do not consider the backpack a part of the person!). (a) if the elevator is not moving, and (b) if the elevator is accelerating downwards at 2m/s2. In each case, what is the magnitude of the normal force exerted on the person by the floor?
If a person steps on a scale in an elevator that is accelerating at a rate 1.300 m/s^2 (negative means downward while positive means upwards) and sees a scale reading of 660.400 Newtons what would the scale read if the elevator were not moving?
You are standing on a scale in an elevator initially at rest and the scale reads 71.2 kg. The elevator begins to ascend and accelerates at a rate of 3.57 m/s 2 . What would the scale read (in kg) when the elevator is moving upwards and accelerating?
A 73.0-kg person stands on a scale in an elevator. What does the scale read (in N) when the elevator is at rest? What does the scale read (in N) when the elevator is climbing at a constant speed of 3.0 m/s? What does the scale read (in N) when the elevator is descending at 3.0 m/s? What does the scale read (in N) when the elevator is accelerating upward at 2.4 m/s2 ? What does the scale read (in...
A 75 kg person is standing on a scale in an elevator. What is the reading of the scale in newtons if the elevator is a) at rest b) moving up at a constant velocity of 2.00 m/s c) accelerating up at 2.00 m/s
Suppose a person with a mass of 60 kg is in an elevator standing on a scale that reads in Newtons. Use a free body diagrams of the scale and the person to determine what the scale would read for the following situations: A. If the elevator is descending at 4.9 m/s. B. If the elevator has a downward acceleration of 4.9 m/s2 . C. If the elevator has an upward acceleration of 4.9 m/s2 . explain WHY
E. Suppose you are standing on the scale in the elevator and the
elevator is accelerating downward with
an acceleration smaller than 9.8 m/s2
i. Draw free-body diagrams of yourself, the scale, and the floor
of the elevator where it interacts
with the scale.
ii. How must the magnitude of the force exerted by the scale on
you compare with your own
weight?
iii. How must the reading on the scale compare with the reading
you make when the elevator...
A 74.0 −kg person stands on a scale in an elevator. What does the scale read (in kg) when the elevator is accelerating upward at 3.2m/s^2? What does the scale read (in N) when the elevator is accelerating downward at 3.2m/s^2? What does the scale read (in kg) when the elevator is accelerating downward at 3.2m/s^2?
