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 612-kg elevator starts from rest and moves upward for 4.50 s with constant acceleration until it reaches its cruising speed, 1.64 m/s. (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
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 615-kg elevator starts from rest and moves upward for 2.90 s with constant acceleration until it reaches its cruising speed, 1.76 m/s. (a) What is the average power of the elevator motor during this period? Incorrect: Your answer is incorrect. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. hp (b) How does this amount of power compare with its power during an upward trip with constant speed? (Give...
A 639-kg elevator starts from rest and moves upward for 3.40 s with constant acceleration until it reaches its cruising speed, 1.78 m/s. (a) What is the average power of the elevator motor during this period? (b) How does this amount of power compare with its power during an upright trip with constant speed?
