How much work does an elevator motor do to lift a 1200 kg elevator a height of 100 m? Express your answer to two significant figures and include the appropriate units. How much power must the motor supply to do this in 60 s at constant speed? Express your answer to two significant figures and include the appropriate units.
Sep 17, 2008· Work = Force x Distance. So in this case you will need to turn the 1000kg into a force. To do that you just multiply the Weight by Gravity. So 1000 x 9.81 = 9810N. Therefore, w = f x d, so w = 9810 x 100 = 981000 Joules. Been looking at my notes and Power = work …
Work is simply the product of force and distance, that is: Work = Force * Distance. In this case, force is simply equivalent to the weifht of the elevator hence: Work = mass * gravity * distance. Work = 1500 kg * 9.8 m/s^2 * 100 m. Work = 1,470,000 J = 1.47 MJ
Gravity does of negative work. Details of the calculation: (a) The work done by the person is W = (100 N)*(3 m) = 300 J. (b) Gravity does 300 J of negative work. Problem: (a) Calculate the work done on a 1500 kg elevator car by its cable to lift it 40 m at constant speed, assuming friction force averages 100 N.
Nov 13, 2019· How much work does an elevator motor do to lift a 1000 kg elevator a height of 100 m at a constant speed? b. How much power must the motor supply to do this in 50 s at constant speed? 1 ... m = 1,000 kg. h = 100 m. 61.b. t = 50 s.
(0.450 kg)(3 m/s²) = 1.35 N. That, in addition to the 4.4 N just to balance gravity means you need 5.8 N upwards force. At 0.05 m radius, that comes out to a torque of 0.28 Nm. There will be some friction and you want some margin, so in this example a 0.5 Nm motor would do it. Note also that torque isn't the only criterion for a motor.
Feb 20, 2013· 1. How much work is required to lift a 2-kilogram mass to a height of 10 meters? A. 5 joules B. 20 joules C. 100 joules D. 200 joules 2. Four machines do the amounts of work listed in the table shown. The time they take to do the work is also listed. Which machine develops the most power? Machine Work Time A 1,000 joules 5sec B 1,000 joules 10sec
A 25.0 kg projectile is fired by accelerating it with an electromagnetic rail gun on the Earth's surface. The rail makes a 30.0 degree angle with the horizontal, and the gun applies a 1250 N force on the projectile for a distance of 7.50 m along the rail.
Work is defined as the displacement of the object due to a force applied upon the object. Work is done when an object moves in the same direction as the force is applied and also when force remains constant. This online Work Calculator helps you find out the work, force or distance based on the other two parameters. Work, force and distance are ...
