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 31.0
mph in time 1.00 s
Part A
At full power, how long would it take for the car to accelerate from 0 to 62.0 mph ? Neglect friction and air resistance.

v Correct
Of course, neglecting friction, especially air friction, is completely unrealistic at such speeds.
Part B
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 31.0 mph in time
1.00 s, how long would it take to go from zero to 62.0 mph ?
