Imagine a 15 kg block moving with a velocity of 20 m/s to the left. Calculate the kinetic Energy of this block.
Show the equation, your work, and the answer with units:

Respuesta :

Answer:

3000 J

Explanation:

Kinetic energy is:

KE = ½ mv²

If m = 15 kg and v = -20 m/s:

KE = ½ (15 kg) (-20 m/s)²

KE = 3000 J

The Kinetic energy of this block will be "3000 J".

According to the question,

Mass,

  • m = 15 kg

Velocity,

  • v = 20 m/s

As we know the formula,

→ [tex]Kinetic \ energy (K.E.) = \frac{1}{2} mv^2[/tex]

By substituting the given values, we get

→                                     [tex]= \frac{1}{2}\times 15\times (20)^2[/tex]

→                                     [tex]= \frac{1}{2}\times 15\times 400[/tex]

→                                     [tex]=15\times 200[/tex]

→                                     [tex]=3000 \ J[/tex]

Thus the above answer is correct.
