I was given a few questions from my teacher to practice for my final exam which is coming up soon, here are the ones I am having troubles with, if anyone can show me how to do em that would be great.
1. Astronauts release two 10.0 kg objects from a space shuttle and place them 10.0m apart, at a location where no other gravitational forces act. The objects are initially at rest. Using Newton's laws and showing your method of calculation, determine the time (h) it will take the gravitational attraction between the two objects to move them 1.00 cm closer together.
and then this one is very hard to explain because there is a picture... its of truck, I'll do my best to explain it.
Use the diagram that shows a truck traveling at a constant speed a long a curve in the road to answer the question.
alright let me explain this... the 1 is a force moving up from the top of the truck.
2 is the force on the tire that is moving ->
3 is the force on the tire moving down
4 is the force on the truck moveing out from its sides
and 5 is the force come from the back of the truck
By number list the forces that are being exerted on the truck and indicate their source.
I have a few more questions but i don't want to hastle anyone, thanks in advance.
