The human heart is a powerful and extremely reliable pump. Each day it takes in and discharges about 7,500 L of blood. Assume that the work done by the heart corresponds to the height of that of the average American woman (1.63 m). In other words, the heart needs to pump blood through her whole height. The density (mass per unit volume) of blood is 1.05 x 103 kg/m³. How much work does the heart do in a day? What is the heart's power output in watts?

A man pushes a lawn mower on a level lawn with a force of 185 N. If 48% of the force is directed horizontally, how much work is done by the man in pushing the mower 5.9 m?
A typical human brain has a mass of 1.4 kg, which makes up about 2% of a person's mass. However, the brain requires 20% of the body's power consumption. In essence, the brain requires 10 times as much power as any other organ in the body. The average power output of the human brain is about 2.0 × 10¹ W. Assume that the brain's power output could be converted into mechanical work and calculate how high we could use this power to lift an apple (m = 0.20 kg) in one minute. Number pa Units

The spring-flex exercise system consists of a spring with one end fixed and a handle on the other end. The idea is that you exercise your muscles by stretching the spring from its natural length, which is 38 cm. If a 170 Newton force is required to keep the spring stretched to a length of 52 cm, how much work is required to stretch it from 51 cm to 70 cm? Your answer must include the correct units. Work =
