A 140 lb person rides in elevator while standing on a scale that reads in slugs. For each part below, draw a free body diagram, write the equations for Newton’s second law and solve.
a.) If the elevator accelerates upward at 2.53 ft/s^2, what is the reading on the scale?
b.) If the elevator accelerates downward at 1.53 ft/s^2, what is the reading on the scale?
c.) If the elevator moves upward at a constant velocity of 2.53 ft/s, what is the reading on the scale?
d.) If the elevator is in freefall, what is the reading on the scale?

You are standing on a bathroom scale and you measure the weight to be 120 lb. You then take the scale onto an elevator and stand on the scale as the elevator accelerates, during which the reading on the scale decreases to 90 lb. Which of the following statements about the elevator could be true? A. The elevator is moving upward at 2 m/s while accelerating downward at 2.45 m/s^2. B. The elevator is moving downward at 4 m/s while...

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

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 person who normally weighs 250 pounds is standing on a scale inside an elevator. The...
A person who normally weighs 250 pounds is standing on a scale inside an elevator. The elevator is moving upward with a speed of 7 m/s and then begins to decelerate at a rate of 5 m/s2(0.5 g). What is the reading on the scale before the elevator begins to decelerate? What is the reading on the scale during the deceleration?

When a 45-kg person steps on a scale in an elevator, the scale reads a steady 480 N. Which of the following statements must be true? (There could be more than one correct choice.) Check all that apply. The elevator is moving upward at a constant rate. The elevator is accelerating upward at a constant rate. The elevator is accelerating downward at a constant rate. From the given information, we cannot tell if the elevator is moving up or down.
