6. 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. 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 from Question 2 above or draw a new one. 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 iniury is likely then write down two physics-base lifting this that avoid

With bumpers touching, a 3,773 kg truck is pushing a 1,103 kg car. The truck and the car move forward together with a maximum forward force of 18,470 N. Assuming friction is zero, what is the magnitude of the force (in N) of the car's bumper on the truck's bumper? Hullo, everyone! I actually know the answer to this question, because I keep getting it marked as wrong - the answer is supposed to be 4178, but for the life of me, I can't figure out how. I thought it would be as simple as finding the acceleration, then multiplying by mass, but I've tried converting kg to g, tried the law of equal and oppositie reaction, tried the car's mass, tried the truck's mass, but I never even get close to the answer I've been given. The AI function on Bartleby, which I have often found quite useful, also can't get 4178. If anyone could send me the specific steps involved in getting this answer, I would be so grateful - thank you so much! 've tried everything with this question.
Astronauts in orbit are apparently weightless. This means that a clever method of measuring the mass of astronauts is needed to monitor their mass gains or losses, and adjust their diet. One way to do this is to exert a known force on an astronaut and measure the acceleration produced. Suppose a net external force of 50.0 N is exerted, and an astronaut’s acceleration is measured to be 0.893m/s2 . (a) Calculate her mass. (b) By exerting a force on the astronaut, the vehicle in which she orbits experiences an equal and opposite force. Use this knowledge to find an equation for the acceleration of the system (astronaut and spaceship) that would be measured by a nearby observer. (c) Discuss how this would affect the measurement of the astronaut’s acceleration. Propose a method by which recoil of the vehicle is avoided.
Express your weight in newtons. From this determine your mass in kilograms.
A girl has a large, docile dog she wishes to weigh on a small bathroom scale. She reasons that she can determine her dogs weight with the following method. First she puts the dogs two front feet on the scale and records the scale reading. Then she places only the dog's two back feet on the scale and records the reading. She thinks that the sum of the readings will he the dogs weight. Is she correct? Explain your answer.

Check Your Understanding Suppose that Balto in Example 2.10 leaves the game to attend to more important matter, but Astro Clifford and Dug continue playing. Astro and Clifford’s pull on the toy does not change, but Dug rims around and bites on the toy in a different place. With how big a force and in what direction must Dug pull on the toy now to balance out the combined pulls from Clifford and Astro? Illustrate this situation by drawing a vector diagram indicating all forces involved.
answers to both question s While we think of weight as "mass", it is actually the pull of gravity on the object. For example, 4.5 kilograms (kg) near Earth is pulled with a force of about 45 newtons, that is, the same force we call "10 pounds" here in the U.S. where the metric system is not as familiar. Now put a 10 lb box at rest on a flat table. What is the total force on the box? mg That's the force of gravity downward on the box. 0 There is no net force on the box. The frictional force F which is μ mg N That's the normal force of the table pushing up on the box. How fast will an object be falling if dropped from rest and allowed to fall for 94 seconds? Use g = 10 m/s2 and give your answer in m/s
