The loaded cab of an elevator has a mass of 3.7 x 103 kg, Ask an Expert

Academics

Q1. The loaded cab of an elevator has a mass of 3.7 x 10^3 kg and moves 228 m up the shaft in 21 s at constant speed. At what average rate does the force from the cable do work on the cab?

Q2. A curve of radius 59m is banked for a design speed of 100 km/h. If the coefficient of static friction is 0.30 (wet pavement), at what range of speeds can a car safely make curve?
