The engine in an imaginary sports car can provide constant power to the wheels over a range of speeds from 0 to 70 miles per hour (mph). At full power, the car can accelerate from zero to 32.0 mph in time 1.20 s. At full power, how long would it take for the car to accelerate from 0 to 64.0 mph ? Neglect friction and air resistance. Express your answer in seconds. ▸ View Available Hint(s) 4.80 s Submit ✓ Correct Of course, neglecting friction, especially air friction, is completely unrealistic at such speeds. Part B Previous Answers A more realistic car would cause the wheels to spin in a manner that would result in the ground pushing it forward with a constant force (in contrast to the constant power in Part A). If such a sports car went from zero to 32.0 mph in time 1.20 s how long would it take to go from zero to 64.0 mph?
