Question
An object is hung from a spring balance attached to the ceiling
of an elevator cab. The balance reads 65 N when the cab is
standing still.What is the reading when the cab is moving upward
(a) with a constant speed of 7.6 m/s and (b) with a speed of 7.6 m/s
while decelerating at a rate of 2.4 m/s2?

- Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.arrow_forwardA huge pendulum is made out of a 8.26-m cable attached at the top to a steel beam. The bottom of the cable is attached to a 38.7-kg anvil that swings back and forth. At the very bottom of its swing, the anvil travels at a speed of 2.53 m/s. Find the tension (in N) in the cable. (You may assume that the cable itself has negligible mass.)arrow_forwardtwo masses are connected by a light string that passing over a frictionless pulley. Mass m1 =3.34kg is on a 50.0-degree incline, and mass m2 =14.2 kg is hanging on the string. the system starts from rest. If the coefficient of the friction between m1 and the incline is 0.878, find the acceleration of the system, in m/s^2.arrow_forward
- A block with mass mb=7.75 kg is suspended on a string. You pull upwards on the string creating a tension force of magnitude TYb=79.2275 N. If the upward speed of the block is 2.25 m/s right now, then what is its speed 5.5 s later?arrow_forwardAn elevator weighing 22 000 N is supported by a steel cable. What is the tension in the cable when the elevator is being accelerated upward at a rate of 3.50 m/s^2? (g = 9.80 m/s^2) Choose answer here (N) 29857 N 27140 N 20000 N 26100 Narrow_forwardConsider a person standing on a scale in an elevator. If the elevator accelerates upwards with an acceleration of 1.27 m/s2 and the person has a mass of 79.2 kg, what would the scale read? HINT: you need to take into account the acceleration due to gravity, as well as that of the elevator.arrow_forward
- A 60.8 kg person is standing inside an elevator. The elevator is moving upward at 3.49 m/s and is decreasing speed at a rate of 1.25 m/s^2. What is the force of gravity that is acting on the person?arrow_forwardConsider 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?arrow_forwardConsider a person standing on a scale in an elevator. If the elevator accelerates upwards with an acceleration of 1.47 m/s2 and the person has a mass of 98.1 kg, what would the scale read? HINT: you need to take into account the acceleration due to gravity, as well as that of the elevator.arrow_forward
- 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?arrow_forwardA 83.2 kg person is standing inside an elevator. The elevator is moving upward at 2.54 m/s and is decreasing speed at a rate of 1.82 m/s^2. What is the normal force that is acting on the person?arrow_forwardA woman stands on a scale while riding in an elevator. When the elevator is at rest, the scale reads 60kg. What will be the reading of the scale in kg when the elevator accelerates. (a) upward at 1.2 m/s^2. (b) downward at 1.2 m/s^2. (c) At what acceleration of the elevator would the person appear to be weightless? Draw the FBD of the problem.arrow_forward
