Vertically Fired Objects Flashcards
1
Q
What must you do with vertically fired objects?
A
Split the problem into 2
The trip up
The trip down
2
Q
Acceleration of the Trip up?
A
it is -9.81 because acceleration is working against the object (it slows down)
3
Q
Acceleration of the Trip down?
A
(free fall)
+9.81
4
Q
Final velocity of the trip up?
A
vf=0
5
Q
Initial velocity of the trip down?
A
Vi=0
6
Q
Relationship between time up and time down?
A
T up= T down
7
Q
Relationship between Initial velocity (up) and final velocity (down)?
A
Vi (up)= -Vf (down)
8
Q
How to solve vertically fired objects?
A
1) Calculate one of them (Typically free fall)
2) If only total time is given, make sure to divide it by two
3) SOLVE!
