A 1000-kg elevator is moving downwards in a skyscraper, with constant velocity. The elevator moves a total distance of 400 m. What is the work done on the elevator cage by the tension of the suspension cable? Take g=9.81 m/s².

Expert Solution

Work done by an object is the magnitude of force multiplied by the distance the object moves,in the direction of force.

work is a scalar quantity.

the negative sign shows that the direction of force and displacement,both are in opposite direction.

A local elevator moves upward at a constant 3.3 mps passing a stopped express elevator. Precisely 2.8 seconds later the express elevator starts upward with a constant acceleration and catches up with the local elevator where the velocity of the local with respect to the express elevator is -9.3 m/s. Determine (a) the acceleration of the express elevator in m/s/s and (b) the distance traveled in m for the express to catch up with the local elevator.

You are designing a high-speed elevator for a new skyscraper. The elevator will have a mass limit of 2400 kg (including passengers). For passenger comfort, you choose the maximum ascent speed to be 18.0 m/s, the maximum descent speed to be 10.0 m/s, and the maximum acceleration magnitude to be 2.70 m/s2. Ignore friction. A). What is the maximum upward force that the supporting cables exert on the elevator car? B). What is the minimum upward force that the supporting...
