(a) Find the useful power output of an elevator motor that lifts a 350000-gload a height of 450 cm in 12.0 s, if it also increases the speed from rest to5.00 m/s. Note that the total mass of the counterbalanced system is 20000kg-so that only 350000 kg is raised in height, but the full 20000 kg isaccelerated. (b) What does it cost, if electricity is S0.0900 per kW · h?

Write the work-energy theorem as follows.
