What is the instantaneous acceleration at t2 = 31 s? I know that the instantaneous acceleration is the slope of the tangent of that point and yes I do know I have to convert it to (m/s^2). But I am still not getting the right answers. Here are a list of answers I imputed and they are all wrong: .1 0 2 1 1.9 1.9 .278 .52 on the first few, I forgot to convert. I used 58/31 the last time..... The question had parts to it, but I don't know if they are necessary to solve this problem...here it is anyways: A) Compute the average acceleration during the time interval t = 0s to t = 10s. 1.7 B) Compute the average acceleration during the time interval t = 30s to t = 40s. 1.7 C) Compute the average acceleration during the time interval t = 10s to t = 30s. 0 What is the instantaneous acceleration at t1 = 29 s. 0 I already computed this and got them right.

It looks like its either going to be 0 or its going to be at that corner, where the rate of change is not going to be defined.
