# The largest asteroid, Ceres, in our solar system's asteroid belt has an estimated mass of 3 * 10^21 kg and an orbital speed of 17900 m/s. What is the asteroid's kinetic energy?

$4.806 \times {10}^{29}$

#### Explanation:

Formula for Kinetic Energy: $\frac{1}{2} m {v}^{2}$

Mass : $3 \times {10}^{21}$ kg
Velocity: $17900$ m/s

$K . E =$ $\frac{1}{2} \left(3 \times {10}^{21}\right) {\left(17900\right)}^{2}$
$K . E =$ $4.81 \times {10}^{29}$
