I switched m for v and isolated for m

The relativistic mass equation shows the relationship between relativistic mass and speed. Basically showing that the closer u get to light speed the less relativistic mass you have, but ur rest mass will be the same. I was asked by my friend what the inverse of that formula means. Thus I...

Hrm.. I guess no one has a copy of it then. Sure u can join. It's every tuesday at lunch in room 112.

My physics club is doing the questions from the 2007 contest, but we don't have the solutions. It's strange because they have solutions for the 2008 ones right now.

Sorry if I posted in the wrong place. Does anyone know where to get the Sir Isaac Newton contest solutions 2007? The site has solutions for 2008, but not of previous years. Thanks.

K, got it thanks.

Im still having trouble with this question. I don't understand the Elastic Pot Energy. Could explain to me the heights you used and why. I don't understand how to get 35.5 m

Homework Statement "A bungee jumper of mass 64.5 kg ( including safety gear) is standing on a platform 48.0 m above a river. The length of the unstretched bungee cord is 10.1 m. The force constant of the cord is 65.5 N/m. The jumper falls from rest and just touches the water at a speed of...

guess I'm right then? Thanks

Homework Statement "The highest waterfall in Canada is Della Falls in B.C., with a change in elevation of 4.4*10^2m. When the water has fallen 12% of its way to the bottom, its speed is 33 m/s. Neglecting air resistance and fluid friction, determine the speed of the water at the top of the...
