How does the pilot of the shuttle control the flight of the spaceship while in orbit? … cars have steering wheels, what does the shuttle have and how does it respond? How does this relate to Newton's Laws?
In a test of a "g-suit," a volunteer is rotated in a horizontal circle of radius of 6.3 m. What is the period of rotation at which the centripetal acceleration has a magnitude of a) 2.5g? b) 10g?
Do you ever sense motion when flying in an airplane in smooth air? If so, when? If not, when? How does this relate to Newton's laws? Fill a cup halfway with water. Walk rapidly across the room at constant velocity … Outside of end effects, what happens to the water? Now put the cup on the table a move it smoothly (starting slow) at a constant velocity across the table … Outside of end effects, what happens to the water? Now accelerate the cup of water across the table … what happens to the water? What does all this tell you about your sense of motion? Can one of you bio experts tell us about how the body uses this phenomenon?
Two adults and a child want to push a crate horizontally in a certain direction (I will denote it as east). One adult pushes with a force of 100 N in a direction of 60 degrees north of east, while the other pushes with a force of 140 N in a direction of 30 degrees south of east. Find the magnitude and direction of the smallest force the child should exert.
A large truck and a small car are in a head-on collision. In which vehicle would you rather be riding? Why? How does this relate to Newton's Laws?
A loaded elevator with very worn cables has a total mass of 1800 kg, and the cables can withstand a maximum tension of 28,000 N. a) What is the maximum upward acceleration for the elevator if the cables are not to break? b) What is the answer to part (a) if the elevator is taken to the moon, where g=1.62 m/s2?
