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

Height of the helicopter, h = 1655.10 meters

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 :

a = g (acceleration due to gravity)

h = 1655.10 m

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

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
