[R] Simulate values

[Osiris10101]

Hello,

I'm facing the following task:
Simulate 500 values of the statistic (n-1)s^2/sigma^2 based on taking 500
samples of size n=40
from the N(mu=10; sigma^2 = 25) distribution.

I think with the following command:
rep(rnorm(40,10,25),times=500)
I was able to simulate the samples but how I now can simulate the values of
the chi-square-distribution is a mystery to me...

I hope anyone can help me, shouldn't be a big problem...

Thanks in advance!

Reason for posting:
I started a course at the University of Manchester and had to catch up with
R, which I never used back in Switzerland. Now I'm solving some exercises to
get more practice and this is one of them.
