When doing any of the calculations can you please show work. 8. If someone told you that astronauts are weightless in orbit because they are beyond

I have attached a document i needed help with. It has a few review questions i got wrong. I need the answers to them so i can compare with what i have done. I also need them to not be copy and pasted from google. The word document needs to be filled in and sent back in word. The last tutor who helped me just copied from google. I could have done this myself. I am looking for a more unique answer then a google search. Thanks for help.

When doing any of the calculaTons can you please show work. 8. If someone told you that astronauts are weightless in orbit because they are beyond the pull of gravity, would you accept the statement? Explain. 9. Why does a pilot tend to black out when pulling out of a steep dive? 2. A curve in a road forms part of a horizontal circle. As a car goes around it at constant speed 14.0 m/s, the total horizontal force on the driver has magnitude 130 N. What is the total horizontal force on the driver if the speed on the same curve is 18.0 m/s instead? 15. A child of mass m swings in a swing supported by two chains, each of length R. If the tension in each chain at the lowest point is ±, Fnd (a) the child’s speed at the lowest point and (b) the force exerted by the seat on the child at the lowest point. (Ignore the mass of the seat.) 26. A skydiver of mass 80.0 kg jumps from a slow-moving aircra² and reaches a terminal speed of 50.0 m/s. (a) What is her acceleraTon when her speed is 30.0 m/s? What is the drag force on the skydiver when her speed is (b) 50.0 m/s and (c) 30.0 m/s?

Great question... View the full answer

Question 1
No
Orbiting astronauts have some weight due to the force of gravity acting on their gravity. This
weight of gravity is the one which causes the astronauts to orbit in circular motion...
