Question

A package is dropped from helicopter moving upward at 13 m/s takes 17.1 s before it hits ground. How high was it?

Answer 1

Height of the helicopter, h = 1655.10 meters

Step-by-step explanation:

It is given that,

Initial velocity of the package, u = 13 m/s

Time taken, t = 17.1 s

We need to find the height of the helicopter. Using the second equation of motion as :

`h=ut+(1)/(2)at^2`

a = g (acceleration due to gravity)

`h=13\ m/s* 17.1\ s+(1)/(2)* 9.8\ m/s^2* (17.1\ s)^2`

h = 1655.10 m

So, the helicopter is at a height of 1655.10 meters. Hence, this is the required solution.
