9000 J

Respuesta :

Answer:

K = 9000 J

Explanation:

Given that,

The mass of a boat, m = 2000 kg

The velocity of the boat, v = 3 m/s

We need to find the kinetic energy of the boat. We know that the kinetic energy of an object is given by :

[tex]K=\dfrac{1}{2}mv^2\\\\K=\dfrac{1}{2}\times 2000\times 3^2\\\\K=9000\ J[/tex]

So, the required kinetic energy is equal to 9000 J.
