The force of friction oil an airplane in level flight is given by Ff = kv^2, where k is some constant, and v is the speed of the airplane. When the power output from the engines is P0, the plane is able to fly at a speed v0. If the power output of the engines is increased by 100% to 2P0, the airplane will be able to fly at a new speed given by (A) 1.12v0 (B) 1.26v0 (C) 1.41v0 (D) 2.82v0 (E) 8v0
