Question

To travel at constant speed a car engine provides 24kW of useful power. The driving force on the car is 600N. At what speed does it travel?

Answer 1

Answer:

Speed of travel of car = 40 m/s..

Explanation:

power p = 24kW = 24 x10³ W

Force F = 600 N

Since speed is constant

Power p = Fx v

speed v = p/F

= 24 x 10³ /600

= 40 m/s
