Question

For problem 18 in chapter 2 of the Giancoli Physics book, 6thedition, I dont understand where the 5/18 fraction came from. Acceleration of the car is 1.6m/s^2. The question is how longdoes it take to go from 80 to 110kmm/h. Any help will be greatly appreciated, and rated.

Explanation / Answer

   Given :    Initial velocity vo = 80 km/h                            [ 1 km = 1000 m & 1h = 60*60 = 3600 s ]                        vo= 80 * (1000m /3600s )                                  = 80 * ( 5m / 18s )       I hope it helps you
