Problem 3PE
(a) Calculate the work done on a 1500-kg elevator car by its cable to lift it 40.0 m at constant speed, assuming friction averages 100 N. (b) What is the work done on the lift by the gravitational force in this process? (c) What is the total work done on the lift?
ANSWER:
Step 1 of 4
We have to find the work done by the cable and work done on lift using the equations
and respectively. And finally we need to find the total work done on the lift.
