Answer:
Kinetic energy, [tex]K=2.53\times 10^6\ J[/tex]
Explanation:
We have,
Mass of the truck is 2500 kg. It is moving with a speed of 45 m/s.
It is required to find the kinetic energy acting on the truck. As it is moving with some velocity, it will have kinetic energy. The kinetic energy of an object is given by :
[tex]K=\dfrac{1}{2}mv^2[/tex], m is mass and v is velocity
[tex]K=\dfrac{1}{2}\times 2500\times 45^2\\\\K=2.53\times 10^6\ J[/tex]
So, the kinetic energy of the truck is [tex]2.53\times 10^6\ J[/tex].
