$\bullet$ $\bullet$ An elevator has mass $600 \mathrm{kg},$ not including passengers.The elevator is designed to ascend, at constant speed, a verticaldistance of 20.0 $\mathrm{m}$ (five floors) in $16.0 \mathrm{s},$ and it is driven by amotor that can provide up to 40 hp to the elevator. What is themaximum number of passengers that can ride in the elevator?Assume that an average passenger has mass 65.0 $\mathrm{kg}$ .

question number 67. In this question, it is given there there is a lift with some persons, the most off the lift scepter limb and the moss off, the person says. And where n is the number of person in the living and is muscle each person does. The total gravitational force on the left is this lift is a test by a motor which resist this lift toe a height off five floors Does the total height covered by the live in US ending is equal to D cause 20 meters. The force by the water on the elevator is f equals, um plus and um T since their Liberatore is moving with constant velocity. So this force is balancing the rate force. They both have equal magnitudes but are in opposite direction. The muscle deliver ter is given as capital M equals 600 kg muscle. 1% is equal to 65 kg. The power delivered by motor is 40 HB that is 40 horsepower. Let tomorrow passengers be in in their lives than Marce off all the persons is and um no using the formula off, Why would wow what the street and US force in tow. Constant. The lost city. The power is given us 40 words power or 14 to 746 words. The constant force is Yep, the lab 600 this and 65 into 9.81 The last e is constant and it can we return us total distance traveled, which is stoned emitters. 10. Time time taken to travel this distance which has given us 16 seconds because we have to solve this expression and find out and on solving it. We get and equals 20 years persons. One thing this to remember here that whenever an object most constant velocity than the net force on the objective zero.
