A clown car is traveling with a velocity of 35 m/s and has a mass of 957 kg. Identify the energy (PE or KE) and calculate the it.

Respuesta :

Given,

The velocity of the car, v=35 m/s

The mass of the car, m=957 kg

The potential energy of an object is related to its position. As the height of the car does not vary with time, the gravitational potential energy of the car is zero.

As the car possesses a velocity, the car will have kinetic energy.

Thus the kinetic energy of the car is given by,

[tex]E=\frac{1}{2}mv^2[/tex]

On substituting the known values,

[tex]\begin{gathered} E=\frac{1}{2}\times957\times35^2 \\ =586.16\times10^3\text{ J} \\ =586.16\text{ kJ} \end{gathered}[/tex]

Therefore the kinetic energy of the car is 586.16 kJ
