5. An engineer wants to design an improved elevator for a building. The original design used a motor that could lift 1000 kg through a distance of 20 meters in 30 seconds. The engineer wants a motor that can lift 800 kg through a distance of 30 meters in 20 seconds. Compared to the old motor, the new motor Explain your answer. (A) Should exert a force of the same magnitude, but must provide larger power Should exert a force of a larger magnitude, output (B) and must provide a larger power output (C) Can exert a force of a smaller magnitude, and can provide a smaller power output (D) Can exert a force of a smaller magnitude, but must provide the same power output (E) Can exert a force of a smaller magnitude, but must provide a larger power output.

Power of the Human Heart. The human heart is a powerful and extremely reliable pump. Each day it takes in and discharges about 7500 L of blood. Assume that the work done by the heart is equal to the work required to lift this amount of blood a height equal to 1.5 m. The density (mass per unit volume) of blood is 1050 kg/m3 . What is the heart's power output. Use g = 9.8m/s2 Calculate answer to one decimal.
A 35.0 kg crate sits on a conveyor belt with s = 0.870. The conveyor belt starts at rest.Once it is turned on, the crate (which follows the belt, so that it stays at rest with respect to thebelt) speeds up to 2.30 m/s in a uniform fashion. How much power does the motor use to turnthe conveyor belt?
A car engine produces a constant power of P = 341 hp. The car and motor have a combined mass of m = 1830 kg. 1.) The car starts from rest, after t=5 seconds, what is the cars speed, you may assume no energy is required to spin the tires. 2.) Assume a dragster of mass m=1000kg can accelerate to cover 450 m and accelerate in 7.2 s from a dead stop, how much horsepower is the engine producing, assuming acceleration is constant?
