Hello, I have a cart going down an air track with an inclination of 7 ° and for some reason my acceleration is going on a downward trend, my velocity is increasing and naturally so is the time. to find velocity I'm using v = (2x)/t and for acceleration I'm using a = (2x) / (t^2). Can you tell mr what I'm doing wrong or what I'm missing? I'm sorry if I'm not being clear if you want I can put the data up for you guys to see. Thank you for your help.
