    MHB Does anyone know the answer to this?

    A simplified model of the power P required to sustain the motion of an electric car at speed v experiencing nonzero drag can be modeled by the equation: P = Av^2 + (B/v) (where A and B are positive constants.) (a) What speed vP minimizes power? (b) What power does the speed in (a) require? (c)...

    MHB Bird Flying Speed at 10m Altitude

    A bird is flying at an altitude of 10m above you, his angular position from your point of view is changing at 0.5 rad · s^-1. How fast is the bird flying when he is directly above you?
