PLEASE HELP!!!!!!
A car slams on its brakes, coming to a complete stop in 4.0 s. The car was traveling north at 60.0 mph. Calculate the acceleration.

Respuesta :

VF=0
Vi=60mph
T=4.0s

you need to convert hours to seconds... so you do there is 60 minutes in an hour and there is 60 seconds in a minute so you do 60*3=180
180/4.0=45m/s^2
