At a construction site, a 62.0 kg bucket of concrete hangs from a light (but strong) cable that passes over a light friction-free pulley and is connected to an 84.0 kg box on a horizontal roof. The cable pulls horizontally on the box, and a 50.0 kg bag of gravel rests on top of the box. The coefficients of friction between the box and roof are the following: μk=0.400 and μs=0.700. The system is not moving. Find the friction force on the box.
An 80 driver gets into an empty taptap to start the day's work. The springs compress 1.8×10-2. What is the effective spring constant of spring system in the taptap.
