Great and anytime, also keep up the work teaching yourself the material I currently am having to do something similar as my school wouldn’t let me in the AP Physics C E&M course.

Probably the result of the first step getting a value of 17.25 instead of the 17.28 that I got, the formula you used for the first stage's displacement I've never seen before and when I solve completely for the problem I reach 31.56 which rounds to 31.6. so maybe there was an error in your math...

Your process is correct however I am assuming you made a mistake in your math while solving through the exact process you described I got 31.6, what were the values you used for the initial velocity for the second stage and the final velocity for the second stage?

Yes, the initial velocity for the second stage is the same as the final velocity for the first. Also I got 17.28 for the displacement of the first stage solved using x = x₀ + v₀t + ½at² = 0 + (20)(.8) + (1/2)(4)(.8)^2 (only the .8 is squared) so I don't know if your teacher considers the .03...

What Physics course are you enrolled in? Because if it is Physics 1 then it more than likely just wants the average velocity for the time period however if you're in a calculus-based physics course it'll want you to find the equation for the derivative of the curve.

Yes, you are so posed to solve for the final acceleration after the first stage and you are correct in saying that the final velocity of the first stage should be 23.2m/s, this is also correct so what I would suggest is using the formula that factors in all your variables and solves your...

Aright thanks for the reply

The problem from the test had no mention of gravity or the speed at any of the given points, however I assumed that gravity is present and the velocity is changing since the that is the type of problems we have covered in my class. Do you think then that it was indeed a problem with the key...
