(a) An elevator of mass m moving upward has two forces acting on it: the upward force of tension in the cable and the downward force due to gravity. When the elevator is accelerating upward, which is greater, T or w? T w Both forces are equal. (b) When the elevator is moving at a constant velocity upward, which is greater, T or w? T w Both forces are equal. (c) When the elevator is moving upward, but the acceleration...
The upward normal force exerted by the floor is 620 N on an elevator passenger who weighs 650 N. What is the magnitude of the acceleration? What is the direction of the acceleration? (upward or downward)
An elevator is pulled upward so it moves with increasing upward speed?the force exerted by the cable on the elevator is constant and greater than the downward gravitational force exerted by Earth. When the elevator is moving up medium-fast, the force exerted by the cable on the elevator changes abruptly to just balance the downward gravitational force of Earth?the sum of the forces that the cable and Earth exert on the elevator is now zero.

_________An elevator suspended by a vertical cable is moving downward but slowing down. The tension in the cable must be A) greater than the weight of the elevator. B) less than the weight of the elevator. C) equal to the weight of the elevator. ______ A bucket is being lowered by a very light rope with a constant downward velocity. The tension in the rope must be A) equal to the weight of the bucket. B) greater than the weight...
Question 4 Part A Predict how the upward force exerted on the feet by the scale will compare to the weight of the man if the elevator is moving upward at a constant speed. The upward force on the feet will be equal to the man’s weight. The upward force on the feet will exceed the man’s weight. The upward force on the feet will be less than the man’s weight. Part B Predict how the upward force exerted on...
The tension in a string from which a 4.0-kg object is suspended in an elevator is equal to 44 N. What is the acceleration of the elevator? Select one: a. 2.4 m/s2 downward b. 1.2 m/s2 upward c. 11 m/s2 upward d. 10 m/s2 upward e. 1.2 m/s2 downward
A fully loaded, slow-moving freight elevator has a cab with a total mass of 1300 kg, which is required to travel upward 47 m in 3.5 min, starting and ending at rest. The elevator's counterweight has a mass of only 800 kg, so the elevator motor must help pull the cab upward. What average power is required of the force the motor exerts on the cab via the cable?
consider an elevator moving vertically with an acceleration a. we wish to find the force exerted by a passenger with mass m on the floor of elevator .
If a 63.4 kg person stood on the floor in an elevator accelerating upward with 0.41g, what would be the magnitude of the force exerted on the floor by the person? (b) What would be the magnitude of the force if the elevator were accelerating downward with 0.54g?
