How long will it take for the car to acceler-

ate uniformly to a stop in exactly 106 m?

Answer in units of s

**Scott**, Wednesday, September 26, 2012 at 1:37pmthe average velocity during deceleration is __ (76 km/h + 0) / 2

the time is the distance divided by the average velocity

you will have to convert km/h to m/s to find the answer in s
