We use them to survive, such as for oxygen, food, and shelter.
You have to move your foot to stop the car so I guess that would be considered work by moving your foot
Motion of things cause the energy such as the nuclear and the chemicals around temperature traveles
The power developed is 500 W ( to the nearest Watt)
Power(P) is the rate at which work is done. Work done (W) is the product of the force applied on the object and the displacement (s) made by the point of application of the force.


Therefore,

Substitute the given values of force , displacement and time


Thus the Power can be rounded off to the nearest value of 500 W
