Thanks! I was able to figure out the correct answer.

So here's what I've tried: force from part (a) / weight = 499.649N / 15kg = 33.310 force from part (b) / weight = 10.511N / 15kg = 0.701 Apparently this wasn't correct. What am I doing wrong? I feel like I'm missing the obvious.

Alright, thank you for your help!

I just started learning physics last week, this was our second real assignment. I hadn't learned how to check my work yet. How should I do the problem instead?

I'm pretty sure the question is asking for the car's acceleration at t = 1s. The answer box on the website has "m/s^2" following it.

I'm not entirely sure that I did this right, but I got 0.4 m/s^2. Is this correct?

I realized I made a mistake when typing out what I did, I meant to just put 0.8 m/s. I still don't understand what to do with this however.

I did (0.9-0.1)/(1.5-0.5) = 0.8/1 --> 0.8 m/s^2 This doesn't look right to me. Is this actually correct or do I need to solve the problem a different way?
