Acar acceleration from rest to a speed of 36 km/hr in 20seconds what is the acceleration of the car in meters per

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
