Vedclass · Answer

(B) The kinetic energy $(KE)$ of an object is given by the formula $KE = \frac{1}{2}mv^2$,where $m$ is the mass and $v$ is the velocity.Since both the car and the truck are moving with the same velocity $(v)$,the kinetic energy is directly proportional to the mass $(m)$ of the object $(KE \propto m)$.Given that the mass of the truck is greater than the mass of the car,the truck will have more kinetic energy.

$A$ car and a truck are moving with the same velocity of $60\, km h^{-1}$. Which one has more kinetic energy? (Mass of truck $ > $ Mass of car).
