The kinetic energy of a car is 8000000 J as it travels along a horizontal road. How much work is required to stop the car in 10s?

8 × 10^6J

Explanation:

Work is a term in physics that describes the process of energy displacement to the movement of an object via the use of a force.

The formula for work is depicted as "Force X displacement" (F * d). The SI Unit is represented as Joule (J)

Given that, the work-energy principle, states that works done by external force equal the change in kinetic energy of the object.

In this situation, we were only given the kinetic energy, therefore, the correct answer still remains 8,000,000 Joules or 8 x 10^6 J.

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
