as long as you have all your angles and then the above lenghts/forces you should be able to do it. do you have a free body diagram of all the strings, angles, lengths, and forces.

ok so for the first one, what equations do you have for x direction and y direction. And since this is a projectile problem what can you assume about acceleration in the y and x direction.

look at your kinematic equations and remember acceleration due to gravity is only in the y direction.

since you are on to work then you know how to sum forces correct? Draw out the free body diagram, sum forces, once you have the forces summed I think you know where to go with it. If not let me know.

what have you done so far? any quess or attempts you have tried?

what are the equations you are using?

have you drawen diagrams for all these. that will help tremendously.

how did you get (-h/5 + h)? I'm not getting that from using the energy equation solving for v.

yes it is looking good, except i think you have some typo's in the last equation line, but i know what you mean.

what is the work you have done? What resultant equations do you have?

but looks like you did use 0.05 to get the answer you have, just have a typo.

15/(2*PI*.005)=47.75rev = 300 radshouldn't 0.005 be 0.05.

ok it says suspended so? hanging from right? You have one mass held up by 2 ropes. those to ropes are not hung straight up, but at angles to the vertical axis. so the ropes form some what of a "V." draw a straight line through the middle of those 2 ropes (through the "v"). where the ropes...

have you drawen the free body with forces?

Y look at 1 minute. It's not answering the question for doubling time. If you are starting with 200, then double would be 400. and the question is what is the time for that. so it would be 400=200e^(0.6031*t). solve for t.
