A boy moves down a waterslide from a height of 10 meters. what is his velocity when he hits the water at the bottom of the slide

statuscvo [17]

The velocity of the boy when he hits the water at the bottom of the slide is 14 m/s.

<h3>Velocity of the boy at the bottom of the slide</h3>

The velocity of the boy when he hits the water at the bottom of the slide is calculated from the principle of conservation of energy.

K.E = P.E

¹/₂mv² = mgh

v² = 2gh

v = √2gh

where;

h is height of the boy
g is acceleration due to gravity

v = √(2 x 9.8 x 10)

v = 14 m/s.

Thus, the velocity of the boy when he hits the water at the bottom of the slide is 14 m/s.

AVprozaik [17]

Answer:

Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells.
