Arunner starts from rest and has an acceleration of 3 m/s how fast is she running after 1.1 seconds?

Initial velocity is 0 m/s
Final velocity needs to be determined

Acceleration is 3m/s2

Using kinematic equation, 
v = u + at
v = 0 + 3 x 1.1
v = 3.3m/s.

Therefore final velocity is 3.3m/s

It's because 3 if it was 10 it wouldn't look right do it goes up to 4d
