Question

A 2600 kilogram car is moving at a speed of 25 m/s. How much kinetic energy does the car have?

Answer 1

Answer:

The kinetic energy of the car $8,12,500\text{ J}$.

Explanation:

Given information:

• Mass of the car $m=2600\text{ kg}$.
• Velocity of the car $v=25\text{ m/s}$.

The kinetic energy of the car is given as,

$K=\frac{1}{2}mv^2$

Substituting all known values,

$K=\frac{1}{2}\times(2600\text{ kg})\times(25\text{ m/s})^2\\=8,12,500\text{ J}$
