    Kinematic Question -- Car braking to avoid hitting a pedestrian

    Homework Statement Driving along a steady speed of 26m/s and suddenly see a child 150m from you. Breaks can produce acceleration of -2.5m/s² but it takes time to get the foot from the gas to the brake pedal. How much time do you have, if to avoid hitting the child? Known: d=150m a=-2.5m/s²...

    B How long to travel 150m at 26m/s with an acceleration of -2.5m/s^2?

    I guess it is how long to travel the distance. I copied the exact question I got.
