# What is the kinetic energy of a 15 g snowball moving through the air at 3.5 m/s?

Apr 22, 2018

$0.091875 J$

#### Explanation:

$m a s s = 15 g = \frac{15}{1000} k g = 0.015 k g$
$v e l o c i t y = 3.5 \frac{m}{s}$

applying the formula,

$K E = \frac{1}{2} m {v}^{2}$

$= \frac{1}{2} \left(0.015\right) {\left(3.5\right)}^{2}$

$= \frac{1}{2} \left(0.015\right) \left(12.25\right)$

$= \frac{1}{2} \left(0.18375\right)$

$= 0.091875 \text{Joules}$

$K E = 0.091875 J$
