Conservation of Energy-Water Slide

Classical Mechanics Level 2

A monkey is sliding down a water slide that has Height ( $h$ ) 10 m high. What is his Speed (in meter per sec) $v$ when he gets to the bottom?* $g = 9.8$

When the monkey reaches the bottom of water slide all its potential energy get convert's into potential energy.

$K.E = P.E$

$\dfrac{1}{2} mv^2 = mgh$

$v^2 = 2gh = 2 \times 9.8 \times 10$

$v^2 = 196$

$v = 14 m/s$

$mgh=\frac{mv^2}{2}$

$v^2=2gh$

$v=√196$

$v=14m/s$
