    A car of mass m is driven with acceleration a along a straight level road against a constant external resistive force R. When the velocity of the car is v, the rate at which the engine of the car is doing work, will be:

    A)  \[(ma-R)\upsilon \]      

    B)         \[(R+ma)\upsilon \]                      

    C)         \[ma\upsilon \]                               

    D)         \[R\upsilon \]

    Correct Answer: C

    Solution :

    We know that power \[=F\times \upsilon =ma\upsilon \]
