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.
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 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?
