The power developed by the engine is given as 750W and the velocity of the car is given as 3m/s. The power developed by an engine can be expressed as the product of force and velocity.
Power = Force × Velocity
Rearranging the equation:
Force = Power / Velocity
Substituting the given values:
Force = 750W / 3m/s
Simplifying:
Force = 250N
Therefore, the force exerted on the car by the engine is (b) 250N.
11. An engine develops a power of 750W while moving a car at constant velocity 3m/s. the force exerted on the car by the engine is (a) 83.3N (b) 250N (c) 750N (d) 2250N
