Question

A rescue helicopter drops a package of emergency ration to stranded party on the
ground. If the helicopter is traveling horizontally at 40 m/s at a height 100m above
the ground, where does the package strike the ground relative to the point at which
it was released? (g = 9.8 m/s)
A. 120 m
B. 130 m
C. 140 m
D. 180.7 m
E. 200.3 m​

Answer 1

Answer:

D. 180.7

Explanation:

H = 1/2gt²

100 = 1/2 (9.8) t²

t² = 100×2/9.8

t² = 100/4.9

t² = 20.4

t = 4.5

X = Vt

X = 40×4.5

X = 180.7
