Question

A car is traveling with a velocity of 40 m/s and has a mass of 1120 kg. The car has ___________energy.

Answer 1

A car is travelling with a velocity of 40 m/s and has a mass of 1120 kg. The car has kinetic energy.

Hint:

If the velocity of a body of mass $m$ be $v$, then its kinetic energy is

$\quad KE=\dfrac{1}{2}mv^{2}$

Step-by-step explanation:

Given, velocity $(v)=40\:m/s$

and mass of the car $(m)=1120\:kg$

Then kinetic energy

$=\dfrac{1}{2}\times 1120\times 40^{2}$ joule

$=\dfrac{1}{2}\times 1120\times 1600$ joule

$=896000$ joule

Answer:

The moving car has 896000 joule energy.
