Answer: 65 J
Explanation:
Kinetic energy is the energy possessed by an object by virtue of its motion.
[tex]K.E.=\frac{1}{2}m\times v^2[/tex]
K.E= Kinetic energy = ?
m= mass of duck = 0.90 kg
v= velocity of duck= [tex]12ms^{-1}[/tex]
Putting in the values we get
[tex]K.E=\frac{1}{2}\times 0.90kg\times (12ms^{-1})^2[/tex]
[tex]K.E=65kgm^2s^{-2}=65Joules[/tex]
[tex](1kgm^2s^{-2}=1Joule)[/tex]
Thus kinetic energy of the duck is 65 Joules.
