thanks for your help!

okay, i see what you mean, I've used that technique before, but the confusion came from two places for me. 1) that I'm dealing with a squared quantity, so would the conversion be 1000cm^2/m^2? 2) that the it's g*cm^2, rather than g/cm^2, leaving me wondering how to actually set up the...

Hello, I need to convert a moment of intertia value given in g*cm^2 to kg*m^2, and was hoping someone could give me a run down of the method behind these kind of conversions. Do I simply assume that since g to kg is a factor 0.001 and cm to m is 0.01, that I can apply a factor of 0.00001 to my...

Okay, I see. Thanks for the assistance.

The first part of a pretty involved, 8 part question on modelling drag force states: "A 0.142 kg ball has a terminal speed of 42.5 m/s. If a ball experiences a drag force of R=CV^2, what is the value of the constant, C? I know this is a ridiculusly easy problem, but our text doesn't cover...

Thank you, thank you, thank you, Brinx! Your reply clears things up immensly, I'll work it through and see if I can get the correct answer.

Actually, no. It's a problem in an online course, you enter your final numerical answer and it either accepts it as correct, or doesn't. My final answer using the method above, was 68.23 s, and I've tried interpreting it in a few different ways, arriving at different answers, but none seem to...

Thanks for your reply, but I'm not sure how to proceed, honestly. Though I do see the relation that you've made between t1 and t2 in terms of Vmax, I really don't understand why you've done this. How is knowing the max velocity pertinent? I can work the equations, solving equation (1) for...

Hello, I've been working on the following problem for quite some time, with no success: A commuter train travels between two downtown stations. Because the stations are only 1.15 km apart, the train never reaches its maximum possible cruising speed. The engineer minimizes the time t between...
