A rescue helicopter drops a package of emergency ration to stranded party on theground. If the helicopter is traveling horizontally at 40 m/s at a height 100m abovethe ground, where does the package strike the ground relative to the point at whichit was released? (g = 9.8 m/s)A. 120 mB. 130 mC. 140 mD. 180.7 mE. 200.3 m​

Answer 1

Answer:

Explanation:

h = 0.5g*t^2 = 100 m.

4.9t^2 = 100

t^2 = 20.40

Tf = 4.52 s. = Fall time.

Dx = Xo*Tf = 40m/s * 4.52s = 180.7 m.
