Question

A rescue helicopter drops a package of emergency ration to stranded party on the ground. If the helicopter is travelling horizontally at 40m/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=9.8m/s2).

Answer 1

Answer:

180m

Explanation:

First we need to find time by the help of height

100: 1/2(9.8)t^2

100: 4.9t^2

100/4.9: t^2

20.48:t^2

Taking root on both sides we get

t: 4.51Sec

Range: voxt

40 * 4.51: 180.4

Round off to 180
