Question 1 Report

\frac{p}{v}

\frac{1}{2}

\frac{p}{v^{2}}

Answer Details

The force provided by the engine is given by the formula P/v. This means that the force is directly proportional to the power provided by the engine, and inversely proportional to the velocity of the vehicle. In simpler terms, if the engine provides more power, the force will increase, and if the velocity of the vehicle increases, the force will decrease. So, to keep a vehicle moving at a constant speed v, the engine needs to provide a force equal to P/v.
