You are standing on a scale in an elevator.
(a) If you feel lighter than usual, what type of motion are you, the scale, and the
elevator experiencing? Explain. Be sure to mention direction of motion and the
forces involved.
(b) When the elevator is at rest, the scale reads 700 N. When the elevator starts to
move, the scale reads 850 N. Calculate your acceleration. You must show all steps for
full marks. "

- In Figure 1, we depict two boxes and an applied force of magnitude 100.0N. The horizontal floor is frictionless, and box A is more massive thanbox B. Which of the following is correct? (Before you answer this question, draw FBDs and sum forces.)a. Box A pushes on box B with a force of 100 N, and box B pusheson box A with a force of 100 N.b. Box A pushes on box B harder than box B pushes on box A.c. Boxes A and B push on each other with equal forces of less than 100.0N.d. The boxes will not begin to move unless the total weight of the twoboxes is less than 100.0 N.arrow_forwardSuppose that Balto in Example 2.10 leaves the game to attend to more important matters, but Astro, Clifford, and Dug continue playing. Astro and Clifford's pull on the toy does not change, but Dug runs around and bites on the toy in a different place. With how big a force and in what direction must Dug pull on the toy now to balance out the combined pulls from Clifford and Astro? Illustrate this situation by drawing a vector diagram indicating all forces involved.arrow_forwardYou pull on a crate using a rope as in (Figure 1), except the rope is at an angle of 20.0 ∘∘ above the horizontal. The weight of the crate is 245 NN, and the coefficient of kinetic friction between the crate and the floor is 0.270. What must be the tension in the rope to make the crate move at a constant velocity? Express your answer with the appropriate units.arrow_forward
- An object of mass m is subjected to three forces: F1, F2, and F3. In the right figure, the three forces are shown in their respective directions. The forces F1 and F3 have a magnitude of F, while F2 has a value of 2F. What is the object's acceleration? Remember that an acceleration is a vector and express it in terms of F and m.arrow_forwardConsider the figure on the left, in which two blocks are being pushed across a frictionless surface. The blocks have masses m1 = 3kg and m2 = 15kg.(a) How hard are you pushing on m1, if the acceleration of m2 is 6m/s2? (You are pushing horizontally, as shown in the figure.) (b) What is the contact force between m1 and m2? (Still focusing on the figure on the left.) (c) Now consider the figure on the right, in which m2 is lifted off the ground. If the coefficient of static friction between m1 and m2 is 0.2 how hard would you have to push the blocks to ensure m2 would not slide down m1?arrow_forwardAccording the 3rd law of motion, you act on the planet Earth with the same amount of force it acts on you with. This is of course the force of gravity. However, if you were to fall down, how come you do not notice the Earth being pulled upward? Suppose everyone in the world jump all at once. Could the jumping move the Earth?arrow_forward
- You are riding on a train. You have a drinks glass in front of you on a table. You notice that the glass, from your perspective, suddenly starts moving towards the front of the train. This appears to violate Newton’s 1st Law of Motion. Explain, using Newton’s Laws, what is occurring.arrow_forwardA wedge with 45° angles is pushed horizontally along a table in the +x direction with a constant acceleration of 3 m/s2. A block of mass 1.0 kg slides down the wedge without friction. Gravity points down, in the -y direction. What is the magnitude of the total acceleration of the block? Give the magnitude of the total acceleration of the block in meters per second squared in the box below. For example, if the block has an acceleration of 1.23 m/s², enter 1.23 in the box. This question has a tolerance of 3%. a = 3m/s²arrow_forwardA ball with mass 0.55 kg is thrown upward with initial velocity 5 m/s from the roof of a building 20 m high. Assume there is a force due to air resistance of magnitude directed opposite to the velocity, where 30 the velocity v is measured in m/s. NOTE: Use g=9.8 m/s² as the acceleration due to gravity. Round your answers to 2 decimal places. a) Find the maximum height above the ground that the ball reaches. Height: m b) Find the time that the ball hits the ground. Time: secondsarrow_forward
