27.  The left ventricle of the heart accelerates blood from rest to a velocity of +26 cm/s. (a) If the displacement of the blood during the acceleration is +2.0 cm, determine its acceleration (in cm/s2). (b) How much time does blood take to reach its final velocity?

 

We know:   ,  , and

 

We need:  a and t

 

For a, knowing , , and x we should use equation

 

Solving for a

 

 

This time we need t, we still have  ,  , and

 

So we use

Solve for t
