Explanation:
photo means light in latin
kinetic means to move
K.E. increases by 9 times
Explanation:
The kinetic energy of a car is given by:

where
m is the mass of the car
v is its speed
From this definition, we see that the kinetic energy depends on the square of the velocity. Assuming that both cars have same mass, m, the kinetic energy of the first car is:

while the kinetic energy of the second car is

if we calculate the ratio, we get
