A particle moves along the curved path sown. if the particle has a speed of 40ft/sec at A at time ta and a speed of 44ft/sec at B at time tb, determine the average values of he acceleration of hte particle between A and B, bath normal and tangent to the path.
I found the average tangent acceleration to the path fairly easy. But I am not sure how to go about getting the normal average acceleration. I Tried to used the average tangential acceleration to get an average acceleration by 20tan(26)-20tan(36), i just am not sure.

My integral says vdv. ignore that it should just be dv.
