Question:
A 1500kg elevator, suspended by a single cable with tension 16.0kN, is measuredto be moving upward at 1.6m/s. Air resistance is negligible.
a) We want to find the elevator's speed after traveling upward 10.0 m. This could be solved with Newton's laws and kinematics, but we will use the energy principle. How much work does tension do on the elevator as it rises 10.0 m? Express your answer with the appropriate units.
b) How much work does gravity do on the elevator as it rises 10.0 m? Express your answer with the appropriate units.
