Answer: its is you figer it out okay haha
Step-by-step explanation: im jokeing
Kinetic energy = 1/2 M V2
At the lower speed, the car's KE is (500) (1)2 = 500 joules
At the higher speed, the car's KE is (500) (2)2 = 2,000 joules
The difference is the energy i.e. the work you have to put into it
to raise the speed from 1 m/s to 2 m/s.
(2,000 - 500) = 1,500 joules there u go :D
