Thank you all for the replies. I'm going to try to summarize what I'm understanding from this thread in hopes that I'll better string everything together: I'm hoping to determine the angular displacement of a hinge acting against gravity given a certain amount of energy upon a collision (with...

Thanks @haruspex for the clarifications! If I were to solve for the angle made must I solve for height? Assume I use energy (see below), would the angular displacement originating from angular velocity be sufficient? In this case, assuming a perfectly elastic collision, would me considering...

Sorry, perhaps I should not have worded it like that. My question was more how I would calculate the maximum height of a rotating object to solve for GPE: use a triangle and the angle? So equating rotational energy and the kinetic energy provided on the hinge to solve for angular velocity, and...

Thank you @haruspex! Thanks for this clarification! I think I'll look at only the latter part of the motion first, with a certain energy and the angular displacement that results. OK, this makes sense. Equate GPE and KE and solve for ##\theta##. I have the kinetic energy given by the spring...

Thank you @ergospherical and @kuruman for the prompt replies! I'm a little bit more lost though... Perhaps I'm misunderstanding this, but just to clarify, I'm looking at a hinged rectangular plate that is separate from the table: the hinge is simply on the table (or else it will dangle freely!)...

Hello! I had a random question while playing around with a garbage can that I hoped y'all could help me walk through: Let's say that I have a hinge on a table, rotating with gravity acting perpendicular to it. Energy is provided into the hinge, let's say by a spring, like so: I want to know the...

Thank you all for the prompt replies! I appreciate your time helping me out. Thank you for clarifying! Is there a way to measure emissivity, or is it difficult to do so; or is this information already common (hence the tabulations in the book)? In terms of my experiment, if the material of the...

As mentioned above, I wanted to devise an equation that can relate the colour of a surface to the temperature on the surface. I tried using the general definition of albedo and combining it with the Stefan-Boltzmann equation (see above, Relevant Equations). However this means that the higher the...
