The best way to solve this is by giving a visual idea of the glass ornaments. so We will have letter G represent Green, O for Orange, B for Brown, P for Purple.
Sample 1:G,O,B,P
Sample 2:G,P,O,B
Sample 3:P,G,O,B
Sample 4:O,G,P,B
Sample 5:G,O,P,B
This is what you can do this should be the right amount of ways to arrange them.

We are given
Tobias dropped a tennis ball from a height of 60 meters. The time in seconds it takes for the ball to fall 60 feet is 0.25(radical60).
so, time is

we have to approximate it's value
First approximation set:
we know that

we can take sqrt all the sides

we can simplify it

Divide all sides by 4

Second approximation set:

Divide all sides by 4


Third approximation set:

Divide all sides by 4


so, we get
