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?
Answered by Henry
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.
