A Car with Constant Power 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 28.0 mph in time 1.50 s
Transcribed Image Text:A Car with Constant Power 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 28.0 mph in time 1.50 s
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 28 0 mph in time 1.50 s how long would it take to go from zero to 56.0 mph? Express your answer numerically, in seconds. View Available Hint(s) Hint 1. How to approach the problem Constant force means constant acceleration Use this fact to find how the speed increases with time IVE ΑΣΦΑΤΑ Ο ?
