# Keeping The School Clean

**Classical Mechanics**Level 2

Juan plans to put a paper ball in the trash can that is at the ground level of his school's building. Juan is on the third floor, \(8.00 \text{ m}\) above the ground level and the trash can is \(8.00\text{ m}\) away from the building where Juan is. If Juan wants to throw the paper ball horizontally, with what velocity should he throw it?

Give your answer in meters per second and take the value of acceleration due to gravity as \( 9.80 \text{ m/s}^2\).

Give your answer to 2 decimal places.
