2. A bird flying horizontally at 10 m/s drops a branch. The bird is flying at an altitude of 20 m. Determine the horizontal displacement it moves relative to where it was dropped.

The horizontal displacement is 20 m.

Explanation:

Given that,

Velocity = 10 m/s

Height = 20 m

We need to calculate the time

Using equation of motion

Put the value into the formula

We need to calculate the horizontal displacement

Using formula of horizontal displacement

Put the value into the formula

Hence, The horizontal displacement is 20 m.
