A helicopter flies 160 m horizontally and then moves downward to land 50 m below. What is the helicopter's resultant displacement?

Displacement = 167.63 m  

Explanation:

Distance refers to the total ground covered by an object while in motion while displacement refers to how far an object is from it's original position.

Now, we are told that the helicopter flies 160m horizontally and then flies 50m downwards.

This means that it's displacement will be the distance from its final position to the initial position.

This can be represented with a triangle attached.

From the triangle, the displacement d will be gotten from pythagoras theorem.

Thus;

d² = 160² + 50²

d² = 25600 + 2500

d² = 28100

d = √28100

d ≈ 167.63 m
