Question

Root-mean-square speed problem

Answer 1

I recently encounter a question in which I use
squart3PV/Nm
and I get 1180m s-1
while I use squart 3kt/m
and I get 1160m s-1
Why is that a difference

Answer 2

They should yield the same answer.. maybe when your calculator rounded up the answers, it gave u that slight difference!
