Answer:
507000 J
Explanation:
According to the work-kinetic energy theorem, the work done is the change in kinetic energy.
[tex]W = KE_2 - KE_1[/tex]
[tex]KE_1 =\frac{1}{2}\times1510\times32.8^2 \text{ J}[/tex]
[tex]KE_2 =\frac{1}{2}\times1510\times20.1^2 \text{ J}[/tex]
[tex]W = \frac{1}{2}\times1510\times(20.1^2 - 32.8^2)\text{ J} = -507231.65 \text{ J}[/tex]
The negative sign indicates work was done on the car.
