Question

Technician A says that the kinetic energy of a vehicle is proportional to its weight. Technician B says that the kinetic energy of a moving vehicle is directly proportional to its speed. Which technician is correct

Answer 1

Technician B

Step-by-step explanation:

The kinetic energy of an object is possessed when it is in motion. It is given by :

`K=(1)/(2)mv^2`

m is mass, v is speed

The kinetic energy is directly proportional to its speed. It does not depend on its weight. It would mean that Technician B is correct as he says that "the kinetic energy of a moving vehicle is directly proportional to its speed".
