2015 F = ma Exam — Question 3

3. The force of friction on an airplane in level flight is given by Ff = kv2, 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
