A car speed up from 18m/s to 34 m/s in 2 seconds
A) find the cars acceleration must write down all given information and show the work
B) What does this acceleration tell us about the motion of the car?

physics 
Elena,
v = vₒ+a•t ,
a = (v  vₒ)/t = (34 – 18)/2 = 8 m/s².
This acceleration tell us that this is the motion at uniform acceleration.
