Question

A car travelling at a constant velocity along a motorway covers a distance of 1.00 km in 50.0 s. To maintain this velocity the car produces a driving force of 230 N. Calculate the effective power of the car engine in maintaining this motion.​

Answer 1

The answer for Power is 4600W or 4.6KW

Step-by-step explanation:

Power is the time rate of doing work

Power=Work done/time

P=F×d/t

convert 1km to m

1km=1000m

P=230×1000/50

P=230000/50

P=4600W

P=4.6KW
