In order to answer this question, it is important to remember and to know the formula for getting the acceleration of an object. The formula for acceleration would be: final velocity - initial velocity -----------------------------------     =   acceleration (meter / second squared) final time - initial time substitute 36 km/hr - 0 ----------------   = meter / second squared 20 seconds convert kilometer and hour to meter and second respectively (36 km / hr) * (1000m / 1 km) * (1 hr / 3600 s) ----------------------------------------------------------   =  meter / second squared                         20 seconds and you get 10 m / s -----------    = meter / second squared 20 seconds then solve which would give you the answer of 0.5 meter / second squared = the acceleration of the car
