Cars a and b have the same mass, but car a's speed is 15 mph, whereas car b is moving at 60 mph. the kinetic energy of car b is: times that of car a times that of car a 2 times that of car a 4 times that of car a 16 times that of car a

16 times that of car A

Explanation:

Moving objects have kinetic energy which is calculated using the formula:

E=(1/2)mv² where m is the mass of the object and v is its velocity.

For car A, kinetic energy =1/2×m×15²

=112.5mi

For car B,  the kinetic energy =1/2×m×60²

=1800mii

dividing ii by i we get

1800m/112.5m= 16.07

Therefore The kinetic energy of car B is 16.07 times that of car A

the answer is b
