an escalator carries you from one level to the next in the airport terminal
how much work does the up escalator do on you when you ride it from the lower level to the upper level?
how much work does the does the down escalator do on you when you ride it from the upper level to the lower level?
Homework Answers
Notice in the second, the movement is downward, gravity is doing the work, the escalator is absorbing it, hence the negative sign.

An escalator moves people from one floor up to another How Escalators Work The height difference between the floors is 4.2 m. The angle of the escalator with the horizontal is 20° The speed of the escalator is 1.2 m/s (along the incline). It is supposed to carry a maximum of 75 people (avg mass-75 kg). The motor running the escalator is 50% efficient. 1. How much work must be done by the motor to move one person up the...

If you just stand still on an escalator (moving stairway), it takes 20 seconds for it to carry you up one floor, about 5 meters. But if you walk up, you get to the top of the escalator in only 12 seconds. (a) How much work does the escalator do in lifting you up to the next floor, it you just stand there? (b) How much if you walk up the escalator? (c) Some people expect the answer in part...

A "moving sidewalk" in an airport terminal building moves at a speed of 1.4 m/s and is of length 35.0 m . A woman steps on at one end and walks at a speed 1.7 m/s relative to the moving sidewalk. How much time does she require to walk from one end to the other if she walks opposite to the direction the sidewalk is moving? Express your answer using two significant figures.

45 kg is released from rest from the top of a rough ramp, with Mass - coefficient of kinetic friction 0.25 between the block and the incline, of height 3.2 m and length d 5.5 m. At the bottom of the ramp, the mass slides on a horizontal, frictionless surface until it compresses a spring of spring constant k 2. 110 N/m. a. Calculate the speed of the mass at the bottom of the ramp? b. How far does...

A car of mass 1100 kg starts from rest at sea level and climbs a hill of height 50.0 m. At the top of the hill, the car has a speed of 25.0 m/s, and at this instant, the driver shuts off the engine of the car. The car then coasts down the other side of the hill to height of 15.0 m above sea level. Assume that friction and air resistance are negligibly small. a) (6 pts) How much...

At the airport, you drag your 17.1 kg suitcase across the floor at a constant velocity using a strap that is at an angle of 47.1o above the horizontal. If the coefficient of kinetic friction between the suitcase and the floor is 0.352, what is the tension in the strap? How much work does the force of kinetic friction do on suitcase if you drag it 20 m? TENSION IN THE STRAP IS 62.9, PLEASE HELP SOLVE FOR WORK.

During a circus act, one performer swings upside down hanging from a trapeze holding another, also upside down, performer by the legs. If the upward force on the lower performer is three times her weight, how much does each of the bones (the femurs) in her upper legs stretch (in m)? You may assume each is equivalent to a uniform rod 35.0 cm long and 1.80 cm in radius. Her mass is 51.5 kg. Assume Young's modulus for bone under...
