A person is standing on a stool inside a dumbwaiter, which is
moving downward and slowing down. The person’s inertia is 20kg and
the stool has an inertia of 10kg. The dumbwaiter itself has an
inertia of 40kg.
(a) Draw a free-body diagram for the dumbwaiter
(b) Draw a free-body diagram for the stool
(c) Draw a free-body diagram for the person.
(d) Does the person feel lighter or heavier at this point? Explain
your answer.

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?
Consider a person standing on a ladder. The ladder is 4 m long, has a mass mı 25 kg, and is leaning against the wall at an angle θ = 70°. The person has a mass m,-75 kg, and their center of mass is located 2.5 m above the ground. a) Draw a free-body diagram, modeling the ladder and person together as one object (i.e. the person will exist in the diagram only as a weight pressing on the ladder)....
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
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...
A man of mass 80 kg is standing stationary in the middle of a train carriage. The train is moving horizontally (towards the right) with a constant speed of 20 m/s, and the carriage is L = 20 m long. Suddenly, the train starts to accelerate uniformly with a = 2 m/s2 horizontally a) Is the reference frame of the train now an inertial frame? Design an experiment that allows you to find out. b) Draw a free-body diagram of...
5) Little Bobby is pushing a cart and the cart starts to slow down, which free body diagram below is correct for the cart slowing down as Little Bobby continues to pushes. A) F FN F D) FN F applied F applied applied F applied 6) Bob applies a force with a magnitude of |F = 160 N to a box downward at an angle = 60° relative to the horizontal, the box has a weight of 196 N and...
Question 2 A small car is driving in a horizontal circle on the inside surface of a cone as shown. The car has mass M and is moving with a constant speed of V. Assume there is no friction acting on the car. The horizontal circle is located at a height H above the point of the cone as shown. The angle between the centre of the cone and the side (the half angle) is ? as shown. a) Draw...
1 Tasks In the class, we showed that a magnet free falling inside a copper tube experiences a braking force that slows down its fall. You are to re-explain this phenomenon using approximate yet sufficient detail math description and validate the explanation using simulation to validate the experimental observation. The tasks are: 1) Refer to the diagram on Appendix A, sketch clearly in your own interpretation of the Faraday's and Lorentz's law in the dash magenta oval in the diagram...

1) Which term best describes an object's resistance to a change in motion A) Force B) Inertia C) Acceleration D) Resistance 2) Two skaters, Cathy and Mike, are standing on a frozen pond. Mike has twice the mass as Cathy. If Mike pushes to the left on Cathy, what can be said about the forces and accelerations on each person? A) Cathy experiences a force and acceleration to the left, while Mike experiences an equal force in the opposite direction....
