how long does it take to fall 500m?
4.9t^2 = 500
now use that t value to find vx using
vxt = 150
you now have the horizontal speed. The vertical speed is
vy = -9.8t
So the speed is (vx^2 + vy^2)
A box containing food supplies for a refugee camp was dropped from a helicopter flying horizontally at a constant elevation of 500. m. If the box hit the ground at a distance of 150. m horizontally from the point of its release, what was the speed of the helicopter? With what speed did the box hit the ground?
