9. A 100 kg man gets in an elevator on the 10th floor. He stands still on a scale, which is placed on the floor of the elevator, before the doors close, and the scale reads a value equal to his weight (the largest force of gravity on him). The doors close, and the elevator starts moving downward toward the 1st floor. The elevator speeds up until it reaches the 8th floor, at which point the elevator travels at a constant velocity, which it maintains until it reaches the 3rd floor, at which point it starts slowing down at a constant rate and stops by the time it reaches the 1st floor. Rank from greatest to least, the following quantities at following floors: 2nd, 5th, 9th. Explain your answers. (a) His mass (the question is asking for a ranking of the person's mass on the 2nd floor vs. the mass on the 5th floor vs. the mass on the 9th floor.) (b) His weight (c) Magnitude of normal force he exerts on the scale (d) Magnitude of normal force he exerts on the elevator floor.

Question

9.
A 100 kg man gets in an elevator on the 10th floor. He stands still on a scale, which is placed on the floor of
the elevator, before the doors close, and the scale reads a value equal to his weight (the largest force of
gravity on him). The doors close, and the elevator starts moving downward toward the 1st floor. The elevator
speeds up until it reaches the 8th floor, at which point the elevator travels at a constant velocity, which it
maintains until it reaches the 3rd floor, at which point it starts slowing down at a constant rate and stops by the
time it reaches the 1st floor. Rank from greatest to least, the following quantities at following floors: 2nd, 5th,
9th. Explain your answers.
(a) His mass (the question is asking for a ranking of the person's mass on the 2nd floor vs. the mass on the
5th floor vs. the mass on the 9th floor.)
(b) His weight
(c) Magnitude of normal force he exerts on the scale
(d) Magnitude of normal force he exerts on the elevator floor.

You are designing a high-speed elevator for a new skyscraper. The elevator will have a mass limit of 2400 kg (including passengers). For passenger comfort, you choose the maximum ascent speed to be 18.0 m/s, the maximum descent speed to be 10.0 m/s, and the maximum acceleration magnitude to be 3.40 m/s 2. Ignore friction. What is the minimum time it will take the elevator to ascend from the lobby to the observation deck, a vertical displacement of 640 m?

Falcons are excellent fliers that can reach very high speeds by diving nearly straight down. To pull out of such a dive, a falcon extends its wings and flies through a circular arc that redirects its motion. The forces on the falcon that control its motion are its weight and an upward lift force—like an airplane—due to the air flowing over its wings. At the bottom of the arc, as shown, a falcon can easily achieve an acceleration of 15 m/s2. Suppose the falcon weighs 8.0 N and is turning with an acceleration of 15 m/s2 at the lowest point of the arc. What is the magnitude of the upward lift force at this instant?A. 8.0 N B. 12 NC. 16 N D. 20 N
