Question

Asked Oct 21, 2019

A helicopter is ascending vertically with a speed of 5.04 m/s . At a height of 124 m above the Earth, a package is dropped from the helicopter. How much time does it take for the package to reach the ground? [*Hint*: What is v0 for the package?] Express your answer to three significant figures and include the appropriate units.

Step 1

**Given information:**

Vertical velocity of the helicopter (u) = 5.04 m/s

Height of the helicopter (h) = 124 m

Let “t” be the time taken for the package to reach the ground

We know that value of “g” is 9.81 m/ s^{2}

Consider upward direction as “+ve” and down ward direction as “-ve”

Step 2

The initial velocity of the package will be equal ...
