♥Part AIf the coefficient of kinetic friction between the box and elevator floor is = 0.32, what magnitude of force must you apply?15. ΑΣΦSubmit Request AnswerN You are riding an elevator on the way to the eighteenth floor of your dormitory. Near theend of your upward trip, while the elevator is going up and slowing down, the magnitude ofthe elevator's acceleration is a = 1.98 m/s². Beside you is the box containing your newcomputer; box and contents have a total mass of 27.5 kg. While the elevator has thedescribed acceleration, you push horizontally on the box to slide it at constant speedtoward the elevator door.

Students are performing an experiment with the setup shown above, where a block of mass M sits on a horizontal table. The coefficient of kinetic friction between the block and the table is μk. The block is connected to a hanging object over a pulley. The pulley has negligible mass and friction. The string connecting the two is very light and does not stretch. The students add mass to the hanging object so that its mass is m, where m < M, and the block-hanging object system is released from rest. The hanging object falls for a distance h, at which point it collides with the ground and comes to rest. The block on the table keeps sliding and travels a total distance d before coming to rest. It does not reach the pulley, and d > h. A student creates a data table (see image) for the net force exerted on the block during the speeding up and slowing down portions of the experiment. (d) Does the block of mass M spend more time speeding up or slowing down? Justify your answer.

Consider two blocks connected . Block A has mass 2.00 kg, and block B has mass 5.00 kg. The table on which B sits is frictionless, the cord connecting the blocks is light and flexible, and the pulley is light and frictionless. The horizontal force F S has magnitude F = 20.0 N, and block B moves to the left with an acceleration of 1.50 m/s2. What is the tension in the cord that connects the two blocks?
An action figure is placed on a toy car, which is initially at rest. Then the action figure moves through 4 time intervals: The car is pushed until it hits a wall. Then, the action figure slides down a ramp. The action figure flies off of the ramp and hits a wall at the peak of its trajectory, momentarily coming to a complete stop. Finally, the action figure falls into the toybox and comes to rest. Assume that all surfaces, except the final wall, have nonzero coefficients of static and kinetic friction. For each time interval, including the endpoints, determine whether the total work done on the action figure by gravity (?g), normal forces (?N), and friction (?f) is positive, negative, or zero. Neglect drag. The motion of a toy army guy action figure is shown in four different time intervals. The toy is stiff and has a base for standing upright. During interval 1, shown in the upper left, the army guy stands upright upon a car initially at rest. The car is pushed to the right,…

A 92.4 kg person is standing inside an elevator. The person is riding the elevator from the 12th floor down to the 3rd floor (a distance of 30.8 m). As the elevator passes the 4th floor it is slows at a rate of 0.620 m/s^2. What is the magnitude of the normal force acting on the person as the elevator passes the 4th floor?

The figure shows two blocks connected by a cord (of negligible mass) that passes over a frictionless pulley (also of negligible mass). The arrangement is known as Atwood's machine. Block 1 has mass m1 = 1.2 kg; block 2 has mass m2 = 1.7 kg. What are (a) the magnitude of the blocks’ acceleration and (b) the tension in the cord?
A 126 kg crate is sitting at the top of a ramp, which is inclined at an angle of 19 degrees with respect to the horizontal. The crate is a height 0.71 m from the ground, measured vertically from the ground to the crate. Someone gives the crate a quick shove to get it moving, after which it slides down the ramp without any further assistance. The coefficient of kinetic friction between the crate and the ramp is ls = 0.23. How much time (in seconds) does it take for the crate to get to the base of the ramp?
A chandelier with mass m is attached to the ceiling of a large concert hall by two cables. Because the ceiling is covered with intricate architectural decorations (not indicated in the figure, which uses a humbler depiction), the workers who hung the chandelier couldn't attach the cables to the ceiling directly above the chandelier. Instead, they attached the cables to the ceiling near the walls. Cable 1 has tension T1 and makes an angle of θ1 with the ceiling. Cable 2 has tension T2 and makes an angle of θ2 with the ceiling. Find an expression for T1, the tension in cable 1, that does not depend on T2. Express your answer in terms of some or all of the variables m, θ1, and θ2, as well as the magnitude of the acceleration due to gravity g. You must use parentheses around θ1 and θ2, when they are used as arguments to any trigonometric functions in your answer.
