the elevator have a mass of 1,325 kg and an upward acceleration of 2.1 m/s^2 , and tension is 15780.75 T
So, The elevator now moves with constant upward velocity of 10 m/s. Find T
Here ,
let the tension in the string is T
for constant velcoity of the elevator
T = m *g
T = 1325 * 9.8
T = 12985 N
the tension in the cable is 12985 N

(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? Tw Both forces are equal. (b) When the elevator is moving at a constant velocity upward, which is greater, T or w? Tw Both forces are equal. (c) When the elevator is moving upward, but the acceleration is downward, which is...

A) 70 kg man s standing in an elevator. Find the reaction of the elevator on the man if a) the elevator is accelerating upward at 1.5 m/s^2 b) the elevator is accelerating downward at 1.5m/s^2 c) the elevator is descending at a constant velocity 3m/s. B) If the elevator and its contents has a total mass of 1500kg, and it is sup four cables each having a tension T. ? find the tension T IN EACH OF THE...
If the elevator was begin to moves upward with the acceleration of 1.3 m/s^2 and was attained the speed of 7.8m/s, then it maintains after 2 seconds which the elevator was begin to move, a boy standing 12m above the initial position of the top of elevator throws a ball upward with an initial velocity of 20m/s. Find the time when the ball will hit the elevator. ( Using calculus based physics)

A 500 kg elevator starts from rest. It moves upward for 2.50 s with constant acceleration until it reaches its cruising speed, 1.75 m/s. a.) What is the average power of the elevator motor during this period? b.) How does this power compare with the motor power when the elevator moves at its cruising speed?
A 500 kg elevator starts from rest. It moves upward for 3.00 s with constant acceleration until it reaches its cruising speed, 1.75 m/s. (a) What is the average power of the elevator motor during this period? W (b) How does this power compare with the motor power when the elevator moves at its cruising speed? Pcruising = W

(a) What is the average power of the elevator motor during this period? hp (b) How does this amount of power compare with its power during an upward trip with constant speed? (Give the power during an upward trip with constant speed.) hp
008 10.0 points An elevator starts from rest with a constant upward acceleration and moves 1 m in the first 1.8 s. A passenger in the elevator is holding a 4.6 kg bundle at the end of a vertical cord. What is the tension in the cord as the ele- vator accelerates? The acceleration of gravity is 9.8 m/s. Answer in units of N.
