Question

A minivan goes from zero to 55 km/h in 12 seconds. Calculate its acceleration. *
our answer

Answer 1

0.762m/s^2

Step-by-step explanation:

Initial velocity(u)=0,final velocity(v)=55, time(t)= 12sec. We know, v = ut + 1/2 gt^2 . Or, 55 = 0×t + 1/2 g 12×12 . Or, 55 = 1/2 g 144. Or, 55= 72g. Or, g = 0.762m/s^2
