# Homework Help: Initial velocity

A car drives at constant velocity on a road. As it comes near a stop sign, the driver brakes, which makes the car decelerate at 4.7 m/s/s. If the car traveled 9.8 METERS while the driver was braking, what was the starting or initial velocity just when the driver was hitting the brakes?

I cant find initial velocity because I cant find the final velocity here. Help please.

The final velocity is zero, the car comes to a stop.
