How much more kinetic energy does your car have when it changes its speed from 16 km per hour to 80 km per hour

The correct answer would be - 25 times more.

Explanation:

The kinetic energy of a moving object increases with the increase in the speed of the object. It is evident that the kinetic energy of a moving object increases as the square of its velocity or speed. It means if a car moves with the speed of 32 km/hr has four times as much kinetic energy as the car moving with 16 km/hr.

Similarly, if a car changes its speed from 16 to 80 km/hr the kinetic energy will be -

= (80/16)^2

= (5)^2

= 25 times more.

Thus, the correct answer would be - 25 times.

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
