Urgent question about acceleration
Car of mass 1250kg travels up a straight hill of length 500m. Its height is 30m. The power of its engine is 30kw and is constant. Its acceleration is 4m/sē at the bottom and 0.2m/sē at the top of the hill. The resistive force is 1kn. Find the gain in KE of the car.
Absurd question right? Why The hell will acceleration decrease. The resultant force is constant. Car is not nearing terminal velocity as they said that the resistive force is 1kn. Then why?
If u think it is absurd, then say that u agree with me. If not, then tell why. Please.
