A helicopter is flying horizontally at 8.15 m/s and an altitude of 18.5 m when a package of emergency medical supplies is ejected horizontally backward with a speed of 10.4 m/s relative to the helicopter. Ignoring air resistance, what is the horizontal distance between the package and the helicopter when the package hits the ground?

Explanation:

Let +y is upward direction and backward be +x direction

then we have given data

From equation simple motion we find the time

So

To get the distance between the point the package ejected to the point it the ground.

Now we have to get the distance the helicopter travels during same interval

Now to get the distance between the package and helicopter when package hit the ground
