# Question #caa2d

##### 1 Answer

#### Explanation:

Let the seagull be flying along the horizontal when it pooped.

Due to gravity poop starts falling in the downward vertical direction. Let the height of the seagull at that instant of time be

As we are required to find out height

1. From the time it started to fall to the time it hits the ground, acceleration due to gravity

2. We ignore drag due to atmosphere.

Initial Potential energy of the poop

When it hits the ground it potential energy

Change in potential energy between the two positions

We know that Kinetic energy

Initial velocity in the vertical is

Final kinetic energy

Change in Kinetic energy

Due to the law of conservation of energy,

Change in potential energy
