During free flight, what is vertical and horizontal acceleration?
Vertical = -9.81 m/s/s
Horizontal = 0 m/s/s
What assumptions are made for calculations during free flight?
Air resistance is insignificant
Gravity is constant
What are the 4 equations of constant acceleration?
v = u + at
v2 = u2 + 2as
s = ut + ½ at2
s = ½ (u + v) t
Which value can remain the same for both vertical and horizontal calculations?
Time
