Free Body Diagrams...help please!
hello hello,
i'm just having a bit of difficulty concerning free body diagrams:
how would i draw an FBD for the following...
a) an object has reached terminal velocity. would this mean that the object has reached a constant velocity, therefore force gravity and air resistance are the same?
b)an object is at the top of a parabolic trajectory. once again, does that mean that the object is simply at a constant velocity and should be drawn with both Fg and Fair resistance as being even. OR...is the object still following and therefore only draw Fg (force gravity)?
c)a ball on a ramp is block from slidding down the ramp. i have the Fn and Fg of the FBD, but I'm just wondering if friction would come in hand in this diagram due to the block.
Assistance greatly needed! :D
thank you!
