A person drive an automobile with a mass of 450 kilograms at a velocity of 26 meters per second. The driver accelerates to a velocity of 30 meters per second. The difference in the automobile's kinetic energy is how many joules?

Answer 1

KE2-KE1 = 0.5M*V2^2 - 0.5M*V1^2 =
0.5*450*30^2 - 0.5*450*26^2 = 202,500 -
152,100 = 50,400 J.

Answer 2

Got eeeem

Answer 3

The answer is 202500

Answer 4

Sorry, my mistake... It is 50,000 J. :)
