Data:
m (mass) = 1 Kg
s (speed) = 3 m/s
Kinetic energy = ? (Joule)


Formula (Kinetic energy)
[tex]E_{k} = \frac{m*s^2}{2} [/tex]

Solving:
[tex]E_{k} = \frac{m*s^2}{2} [/tex]
[tex]E_{k} = \frac{1*3^2}{2} [/tex]
[tex]E_{k} = \frac{1*9}{2} [/tex]
[tex]E_{k} = \frac{9}{2} [/tex]
[tex]\boxed{\boxed{E_{k} = 4.5\:J}}\end{array}}\qquad\quad\checkmark[/tex]
