t = time of free fall = 35 s
Horizontal distance
= horizontal speed × duration of free fall
For the vertical component of free fall,
Vyi=initial vertical velocity = 0
a=vertical acceleration = -g = -9.8 m/s²
ΔY = vertical position change
ΔY = Vyi(t)+(1/2)at²
Substitute numerical values to calculate required distances.
You're in an airplane that flies horizontally with speed 830km/h (230m/s ) when an engine falls off. Neglecting air resistance, assume it takes 35s for the engine to hit the ground.
Find the height of airplane.
