Acceleration of blood pumped by heart

[melinaamos]

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).

Hi melinaamos ! Welcome to PF!

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?

Hey,

i'm using v2= vo2 + 2ax but still getting the answer wrong

Hi melinaamos!

Well, that's the right formula.

Show us your working, so we can check it.
