2016 F = ma Exam — Question 11

The power output from a certain experimental car design to be shaped like a cube is proportional to the mass m of the car. The force of air friction on the car is proportional to Av2, where v is the speed of the car and A the cross sectional area. On a level surface the car has a maximum speed v . Assuming that all versions of this design have the same density, then which of the following max is t
