The distance you free-fall from rest is D = (1/2) (g) (T²) <== memorize this
Height of the platform = (1/2) (9.8 m/s²) (2.4 sec)²
Height = (4.9 m/s²) (5.76 s²)
Height = (4.9/5.76) meters
Height = 28.2 meters (a VERY high platform ... about 93 ft off the water !)
Without air-resistance, your horizontal speed doesn't change. It's constant. Traveling 3.1 m/s for 2.4 sec, you cover (3.1 m/s x 2/4 s) = 7.4 m horizontally.

Answer:
v1=18.46m/s
v2=29.8cm/s
Explanation:
We know that
the equation of the motion is
we can calculate w by using
Hence, we have that
the speed will be

Answer:
they use thermals and air currents to glide.
Explanation:
when they flap higher they use thermals and air currents because flapping takes a lot of fuel,energy
