the work required to strech the spring from 10 to 20cm is more than required to strech it from 0 to 10cm, according to Hookes Law
how much does it take to strech from 0 to 10?
how much does it take to strech fom 10 to 20?

I'm 13 and I broke my leg, so I'm on home school so I don't have a teacher to ask questions to.

Force changes as the spring is being stretched the distance, so the energy = x * f/2 = kx^2/2.
0 to 10 = 50*0.01/2 = 0.25 J
0 to 20 = 50*0.04/2 = 1 J
10 to 20 = 50 * (0.04-0.01)/2 = 0.75 J

Work is force*distance so to stretch the fist ten centimeters, the force is kx = 50N/m * .1 m = 5 N
work is f*dist = 5N*.1m = 0.5J
from 10 to 20 the force is kx=50N/m*.2m = 10N
work if f*dist = 10N*.1m = 1 J

May I ask how old are you? Look up hookes law, and plug in the numbers.
