2. You need to lift a person with a mass of Z kilograms who is laying in bed into a wheelchair next to the bed. If the distance from your hand to your elbow is Y centimeters and the distance between your shoulder and lower back is Z centimeters, how much force will your lower back muscles experience if you lift by leaning over the wheelchair? Sketch a diagram to help explain your reasoning, and show your calculations. 3. Referring to Question 2 above, how much force will your lower back muscles experience if you lift by sliding the person in a seated position into the wheelchair while you maintain as upright a position as possible? Refer to the diagram from Question 2 above or draw a new one.
