A car is initially traveling at 50.0 km/h. The brakes are applied and the car stops over a distance of
35 m. What was magnitude of the car's acceleration while it was braking?



for this problem i know you have to use V= (Vf^2 - Vo^2)/2a



how do you figure out the initial velocity after the breaks are applied?

You mean to say: x - x0 = (Vf2 - V02)/2a

how do you figure out the initial velocity after the breaks are applied?
It is given: 50km/h
