In the course of a short race, a car does 50,000 J of work in 7 s. What is the power of the car during the race? (round to the nearest whole number)

Respuesta :

127605me

Answer:

Work done is the product of distance and force, it is measured in joules.

Power is the rate of work done given by dividing the work done by time

Power (watts)= workdone (J)/ time (s)

                     = 50,000J/7 sec

                     = 7142.857 watts

Therefore, the power of the car during the race was 7142.857 watts
