An elevator cab has a mass of 4510 kg and can carry a maximum load of 1910 kg. If the cab is moving upward at full load at 3.80 m/s, what power is required of the force moving the cab to maintain that speed? Number Units

A force } = (cx – 3.00x2) acts on a particle as the particle moves along an x axis, with in newtons, xin meters, and ca constant. At x = 0 m, the particle's kinetic energy is 20.0 J; at x = 3.00 m, it is 12.0 J. Find c. Number Units
