Question

Use the GUESS method to solve the problem below.

Little baby bird is in a nest that is up in a big oak tree. Mama bird flies back to hungry little baby bird with a fat, juicy worm. In his haste, little baby bird drops the worm and sadly watches it fall to the ground below in 0.75 seconds. how high is the nest?

Answer 1

2.75 m

Step-by-step explanation:

Given that,

Little baby bird drops the worm and sadly watches it fall to the ground below in 0.75 seconds.

We need to find how high is the nest. Let it is h. It can be calculated using second equation of motion as follows :

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

Here, u = 0 and a = g

`h=(1)/(2)gt^2\\\\h=(1)/(2)* 9.8* (0.75)^2\\\\h=2.75\ m`

So, the nest is 2.75 m high.
