power = 40hp =29828w
P=work done divided by time
=>P=dW/dt=F.v where f is the force and v is the velocity
v=d/t=20/16=1.25m/s
=>F=P/v=29828/1.25=23862.4 N
This F is the force applied by the elevator to carry itself and the passengers
These forces are:
Weight of the elevator Wele=600*9.81=5886N
Weight of the passengers Wpas=9.81m
=> F-Wele-Wpas=ma
for this elevator to hold the maximum number of passengers it means that the force applied by the weight of the elevator plus that of the passengers must be equal to the force provided by the motor thus rendering the elevator at rest => acceleration (a)=0
=>F-Wele-Wpas=0
=>23862.4-5886-9.81m=0
=>9.81m=17976.4
=>m=1832.5kg
If the average mass of a passenger is 65
=>maximum number of passengers that can ride in the elevator are
1832.5/65=28.2
=> approximately 28 passengers can ride in the elevator
What else can I help you with?
Does perpendicular lines have a constant distance between them?
No but parallel lines have a constant distance between them
How do you find the constant speed of something?
If you know that the speed is constant, just divide the distance by the time it takes to travel that distance.
A collection of points in the plane whose distance from fixed point is constant?
That's a circle. The "fixed point" is the center of the circle, and the constant distance is its radius.
How can you determine the speed of an object that has constant motion if you have a distance vs time graph of the motion?
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
What is the stopping distance of a 2010 ford explorer at 25 miles per hour?
The stopping distance depends, not only on the car and its speed but also onthe reflexes of the driver,the mass of the car INCLUDING all passengers and luggage,the condition of the brakes,the tread on the tyres, andthe condition of the road.

No but parallel lines have a constant distance between them
Is the total distance traveled divided by constant speed eual constant speed?
No. The total distance traveled divided by constant speed is the time interval.
Is the distance for mercury to the sun constant?
The distance form Mercury to the Sun is not constant because Mercury's orbit is not a perfect circle. The average distance is 35,980,000 miles.
How do you find the constant speed of something?
If you know that the speed is constant, just divide the distance by the time it takes to travel that distance.
What is the equation for constant speed?
The equation for constant speed is distance = speed x time, where distance is the total distance traveled, speed is the constant speed at which the object is moving, and time is the duration of travel.
What is the equation for calculating speed when you know distance and time?
distance = speed x time.This assumes a constant speed.distance = speed x time.This assumes a constant speed.distance = speed x time.This assumes a constant speed.distance = speed x time.This assumes a constant speed.
When an object is traveling the same distance every second it has a?
constant speed
What is the formula for calculating distance when an object is accelerating at a constant rate, given by the equation distance 1/2at2?
The formula for calculating distance when an object is accelerating at a constant rate is distance 1/2 acceleration time squared.
A collection of points in the plane whose distance from fixed point is constant?
That's a circle. The "fixed point" is the center of the circle, and the constant distance is its radius.
How can you determine the speed of an object that has constant motion if you have a distance vs time graph of the motion?
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
How do you find constant speed?
You didn't specify what data is given. In general, for constant speed, the following formula is important (just use the definition of speed): speed = distance / time; or distance = speed x time. If distance is in km and time in hours, speed will be in km/hour; if distance is in meters and time in seconds, speed will be in meters/second.
What is the stopping distance of a 2010 ford explorer at 25 miles per hour?
The stopping distance depends, not only on the car and its speed but also onthe reflexes of the driver,the mass of the car INCLUDING all passengers and luggage,the condition of the brakes,the tread on the tyres, andthe condition of the road.
