Homework Statement



Find average value of Normal Acceleration from the information given. (See the picture)

Homework Equations



a^{→}_{ave}= Δv^{→}/Δt

a_{t}=Δv/Δt


The Attempt at a Solution



I took the difference of the given angles in radians and divided it twice by Δt and get 3.6 rad/s^{2} but the answer was wrong as expected. Please help.

hi gikiian! :smile:

no, rad/s2 is angular acceleration, isn't it?

you need the normal component of the ordinary (linear) acceleration :wink:
 
Hey tiny-tim!

I have successfully obtained the linear acceleration vector. Would you now like to tell me with respect to what entity should I compute the normal component of it?

my inclination would be to use the direction halfway between the two velocities
 
You can'y do that.
