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?
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.
