Homework Statement 1. You create a plot and the linear trend is y = 3.75 x + 0.135. The plot is titled "Work [Joule] versus Position [meter]". Write the "physics" translation for this plot's trendline. Homework Equations y = 3.75 x + 0.135. Find physics equation. The Attempt...

You're right, I mistyped and F=Tcos30. Sorry about that. I seem to be stuck in this rigid mindset from other science classes that there is a sequential set of steps to solve every problem. Definitely finding that's not the case and there are multiple options (within limits) for the same problem...

Ah, ok. So really you can take these 2 equations that you've "generated" and use them in any way necessary to isolate and solve for variables.

Edit.

Yes, the force F is horizontal. ƩFx = F - Tx = 0 so F = Tx since Tx = Tsin30, F=Tsin30 ƩFy= Ty - W = 0 so Ty - w = 0 Ty = w Tsin30 = w So, in this instance, it turns out that the x and y components of the tension force are equal to F and W, respectively. So that's all I should be...

First time taking physics in many years, so please forgive the simplistic nature of this problem. A 2.0 kg ball tied to a string fixed to the ceiling is pulled to one side by a force F. Just before the ball is released, (a) how large is the force F that is holding the ball in position and (b)...
