# A car acceleration from rest to a speed of 36 km/hr in 20seconds what is the acceleration of the car in meters per second,,?

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
