The cable lifting an elevator is wrapped around a
How long does it take for the elevator to stop?
Circumfrence of the cylinder:
C = (2)(3.14)(1.1/2) = 3.4558 m
v2 = v02 + 2a(∆x)
In this case the circumfrence length will be ∆x
v = 2.3 m/s
v0 = 0
2.32 = 0 + 2a(3.4558)
a = 5.29/(2*3.4558)
a = 0.76539
v = v0 + at
2.3 = 0 + (0.76539)t
t = 2.3/0.732.6
t = 3.0 s
The cable lifting an elevator is wrapped around a 1.0-m-diameter cylinder that is turned by the elevator's motor. The elevator is moving upward at a speed of 1.7 m/s . It then slows to a stop, while the cylinder turns one complete revolution. How long does it take for the elevator to stop? Express your answer to two significant figures and include the appropriate units. Thanks for the help!
A cable lowers a 1400 kg elevator so that the elevator's speed increases from zero to 4.0 m/s in a vertical distance of 5.6 m . What is the force that the cable exerts on the elevator while lowering it? (Assume that the system is the elevator and Earth.) What is the force that the cable exerts on the elevator while lowering it? (Assume that the system is the elevator only.)
A cable lowers a 1150 kg elevator so that the elevator's speed increases from zero to 4.0 m/s in a vertical distance of 6.4 m What is the force that the cable exerts on the elevator while lowering it? (Assume that the system is the elevator and Earth.) Express your answer to two significant figures and include the appropriate units. What is the force that the cable exerts on the elevator while lowering it? (Assume that the system is the...
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?
An elevator is initially moving upward at a speed of 13.08 m/s. The elevator experiences a constant downward acceleration of magnitude 4.16 m/s2 for 2.79 s. (a) Find the magnitude and direction of the elevator's final velocity. magnitude direction ---Select--- upward downward none (b) How far did it move during the 2.79 s interval?
Chapter 07, Problem 049 A fully loaded, slow-moving freight elevator has a cab with a total mass of 1800 kg, which is required to travel upward 45 m in 4.7 min, starting and ending at rest. The elevator's counterweight has a mass of only 860 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? Number the tolerance is +/-3% Units
An elevator is initially moving upward at a speed of 12.60 m/s. The elevator experiences a constant downward acceleration of magnitude 3.92 m/s2 for 2.97 s (a) Find the magnitude and direction of the elevator's final velocity. magnitude direction !--Select--# (b) How far did it move during the 2.97 s interval?
on a (a) The elevator accelerates upward from rest at a rate of 1.25 m/s? for 1.50 s. What does the scale read during this 1.50s interval? (b) The elevator continues upward at constant velocity for 8.50 s, what does the scale read nos? (c) While still moving upward, the elevator's speed decreases at a rate of 0.700 m/s? for 3.00 s. What is the scale reading during this time? Tutorial In an exciting game, a baseball player manages to...
A skyscraper in Manhattan has an elevator that weighs 1000 kg when loaded. The elevator is lifted at a constant rate to 480m above the ground by an electric winch motor. The drum of the winch motor is a solid uniform cylindrical drum in which a steel cable can wrap around it. The mass of the drum is 500 kg and has a diameter of 1 m. It takes the elevator a total of 120 s to get to the...
