An elevator is able to raise 1000kg to a height of 40m in15s.(a) How much work does the elevator do?(b) What is the elevator's power output?
A 900 kg elevator accelerates upward at 1.3 m/s2 for 11 m, starting from rest. You may need to review (Page 206) Part A How much work does gravity do on the elevator?Part B How much work does the tension in the elevator cable do on the elevator? Part C What is the elevator's kinetic energy after traveling 11 m?

A 500 kg elevator accelerates upward at 2 m/s2 for 17 m, starting from rest. A) How much work does gravity do on the elevator? B) How much work does the tension in the elevator cable do on the elevator? C) What is the elevator’s kinetic energy after traveling 17 m?
(a) Find the useful power output (in W) of an elevator motor that lifts a 2800 kg load a height of 35.0 m in 12.0 s, if it also increases the speed from rest to 4.00 m/s. Note that the total mass of the counterbalanced system is 10,000 kg-so that only 2800 kg is raised in height, but the full 10,000 kg is accelerated. (b) What does it cost (in cents), if electricity is $0.0900 per kw-h? cents Additional Materials...
Find the useful power output of an elevator motor that lifts a 2500-kg load a height of 35 m in 17 s, if it also increases the speed from rest to 4.25 m/s. Note that the total mass of the counterbalanced system is 10,000 kg--so that only 2500 kg is raised in height, but the full 10000 kg is accelerated.
_10. You and your BFF (combined mass of 200 kg) are taking an elevator to your physics lecture. The elevator car has a mass of 1,600 kg. A constant friction force of 4,000 N retards the elevator's motion. How much power must the motor deliver to lift the elevator car and its passengers at a constant speed of 3.00 m/s? a. 6.49 x 104 W = 200kn P U b. 1.24 x 10 W c. 5.33 x 10 W d....

An elevator mass of 2600 kg falls from a height of 25 m after a sudden failure in the hoisting cable. The mass is stopped by a spring at the bottom of the shaft having a spring constant of 90 kN/m. Determine the spring's compression distance (in m) that brings the falling elevator momentarily to rest. An elevator mass of 2600 kg falls from a height of 25 m after a sudden failure in the hoisting cable. The mass is...
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.)
