Question

What is the kinetic energy of a 200 kg object that is moving at a velocity of 15 m/s?3000 Jb30,0000 Jc215 Jd2150 J

Answer 1

22500 Joules

Step-by-step explanation

Kinetic energy is a form of energy that an object or a particle has by reason of its motion and mass ,

`E_k=(1)/(2)mv^2`

where m is the mass of the object and v the velocity

Step 1

a)Let

`\begin{gathered} m=200\text{ Kg} \\ v=15(m)/(s) \end{gathered}`

now, replace

`\begin{gathered} E_k=(1)/(2)mv^2 \\ E_k=(1)/(2)(200\text{ kg\rparen\lparen15}(m)/(s))^2 \\ E_k=(1)/(2)*45000\text{ Joules} \\ E_k=22500\text{ Joules} \end{gathered}`

so, the answer is 22500 Joules
