- Homework Statement
- The cable of a 4,000 kg elevator snaps when the elevator is at rest on the first floor so that the bottom is a distance d = 12.0 m. A safety device claps the guide rails so that a constant frictional force of 10,000 opposes the motion of the elevator.(g=10 m/s^2)
a) What is the speed of the elevator just before it hits the ground?
- Relevant Equations
- PLEASE DON'T SOLVE THIS USING CONSERVATION OF ENERGY METHOD...IF POSSIBLE SOLVE THIS USING THE FORCE VELOCITY RELATION(F=vdv/dx)
