The integrals are no so complicated... but in another forum someone told me that the proton never leaves and the path i guess it's not a straight line, because qE is diferent that q(vxB) [q(vxB) and qE are in opossite directions but they aren't equals to eliminate them...]
But in the problem exist an E field... the trajectory doesn't have to be exact... i guess it's a Uniform Circular Movement.
If i'd do:
First for t=0 -> x=0 y=0.05
Then:
Finding t=? for x=0.3 y=0.05
That would be correct¿? then i replace that value of t in the formula of the speed...
Well just replace with the values given...I'm stuck i don't know if that's correct or not... I decided do it with all variables and then replace them...
I guess i sould integrate the speed getting the position (x,y) but I'm not sure if that's correct...
I need help.. I HAVE to resolve...
Yeah ok, I'm newbie in this forum... that's what i did :

But i don't know what else to do.. please help me =)
Homework Statement
