Hey,
I"m having a few problems with some motion problems and was wondering if someone could help?

The left ventricle of the heart accelerated blood from rest to a velocity of +23.9 cm s-1. If the displacement of the blood during the acceleration is +1.80 cm, determine its acceleration (in cm s-2).

Welcome to PF!

Hi melinaamos ! Welcome to PF! :smile:

vi = 0, vf = 23.9, x = 1.8.

(btw, you should have used the standard form for homework questions)

Hint: what equations do you know relating vi, vf, x and t? :smile:

Well, that's the right formula.
