hard problem, a car traveling 95.0 km/hr needs to decelerate at 4.2m/sec/sec. reaction time of driver is 1.2 sec. what is original speed of driver in m/sec, total distance in m. needed to stop.

so the reaction distance + deceration distance what they're looking for

use this formula x1 = xo + vocost = ?

any thoughts
