6. You need to lift a person with a mass of 103 kilograms who is laying in bed into a wheelchair next to the bed. If the distance from your hand to your elbow is 14.8 centimeters and the distance between your shoulder and lower back is 103 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. 7. Referring to Question 6 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 you drew for 6. 8. Referring to Questions 6 and 7 above, is it likely you will injure your lower back muscles in either lifting activity? Explain quantitatively why or why not, citing all references you use. If injury is likely, then write down two physics-based ways of lifting this patient that avoid injury
