Suppose a 1350-kg elevator car is lifted a distance 43 m by its cable at a constant speed, assuming the frictional force on the elevator has a constant value of 1525 N.Calculate the work done on the elevator by its cable, in joules.
Added by Aydan G.
Step 1
Substitute the values: T = 1525 N + 1350 kg * 9.8 m/s^2 Calculate the tension: T = 1525 N + 13230 N T = 14755 N Show more…
