Two runners start in opposite directions at the northernmost point of a circular track 20.0 m in radius. If the speed of each runner is constant and is 5.31 km/h for Runner A and 3.44 km/h for Runner B, where will they meet? Where will they meet the second time? Assume that they go around the track on essentially the same path, with Runner A initially headed west and Runner B initially headed east.

This should be really simply but I can't figure it out... the problem is: A car is driving along at 11 m/s, and the rain is falling at 3 m/s straight down. What angle q (in degrees) does the rain make with respect to the horizontal as observed by the driver

If someone could even tell me how to set this up it would be a great help... i'm completely lost

Hi. Does anyone know how to solve this?
On a planet you find that a 16.4 kg object falls downward 6.0 m in 3.2 seconds. What is the magnitude of acceleration due to gravity? How much does the object weigh on this planet? How much would this object weigh back on earth?
Thanks!

your stating point of motion was on earth ,now the observer on earth will see that you as you traveltime has dilated and your your distance traveled has contracted(per time dilation and lenght contraction formula) He we see your velocity as zero dived by long time diltation .Hence zero velocity means he sees you standing Still?

I am looking for devices, like springs, bows, that convert the elastic energy to kinetic energy.

I also would like to know how they work, with physical equations.

All I was wanting to do today was visit the Physics chat, now that I have studied up on Dark Matter...and enjoy the intellectual flow of conversation.... but, It was all about dating, not science...I was asked if I had a web cam and all I wanted was Q & A about Astrophysics. No one would talk to me about science. bummer...anyone want to chat IM just for relaxing...I have physics jokes as well....ah well...I was just let down I guess.
