Data:
m (mass) = 1 Kg
s (speed) = 3 m/s
Kinetic energy = ? (Joule)
Formula (Kinetic energy)
\(E_{k} = \frac{m*s^2}{2}\)
Solving:
\(E_{k} = \frac{m*s^2}{2}\)
\(E_{k} = \frac{1*3^2}{2}\)
\(E_{k} = \frac{1*9}{2}\)
\(E_{k} = \frac{9}{2}\)
\(\boxed{\boxed{E_{k} = 4.5\:J}}\end{array}}\qquad\quad\checkmark\)
