Acar accelerates from rest at 2 m/s^2. what is the velocity at 8 seconds.

16 m/s

Explanation: In order to solve this problem we have to use teh following kinematic expression:

Vf=Vo+a*t whre Vf and Vo are the final and initial velocity. In our case Vo=0

so Vf= a*t= 2 m/s^2*8s= 16 m/s

not really sure but thinking 1.54 mm/us
