Well, I'll try :) So ball starts from rest, so Xo = 0, Vox = 0, T1 = 0. Then the ball rolls 5s and it's place is X1 and V1x = ?. Finally the ball rolls the second 5s and then X2 = X1 + 150m, V2x = ? and T2 = 10s When the ball rolls first 5s: (1) X1 = 1/2(AxT1^2) The ball rolls second...

Yeah, I have tried those equations, but I can't get the right answer...

I'm learning physics and I'm now working on with one line motion problems and I'm jammed with this one problem: A ball starts from rest and rolls down a hill with uniform accelration, traveling 150m during the second 5.0s of it's motion. How far did it roll during the first 5.0s of motion...

Thanks Andrew! That works great! :)

Oh, yes it's ideal gas. I forget to mention that :) Do I need to calculate v1= nRT/1atm and then v2= nRT/3atm?

Yes, it probably should, but I'm very dumb with physics :P I already tried to find some help from Google but I didn't have any luck :/

Hello! Any ideas how I could solve this exercise: 5 mol of gas is in temperature of 326K and the same time the pressure is expanded from 1atm to 3atm. How much work is done by the gas? Detailed instruction would be good, thanks :)
