Homework Statement
At the height of H, from a plane with the speed of V, there is an object "thrown off".
H = 10km = 10 000m
V = 300m/s
To be determined:
- total distance from the plane to the falling point - S
- the time the fall takes - T
do not have to take aerial friction into account
Homework Equations
s = v0t + at²/2
The Attempt at a Solution
-Take the positive direction of movement as movement from the ground to the sky
-horizontal acceleration = 0 , vertical acceleration = -g = -9.8m/s²
the total distance is the sum of the distance traveled vertically and horizontally (sum of 2 vectors that is or that would make sense atleast)
so S² = (VT)² + (-gT²/2)²
But I have 2 unknowns and 1 equation. What will I have to do next?
Also I apologise in advance - I don't know all the mathematical terminology in English that well, so some things may seem a bit confusing :/
Cheers
