1) The diagram below shows a 0.1-kilogram apple attached to a branch of a tree 2 meters above a
spring on the ground below. The apple falls and hits the spring, compressing ito. I meter from its rest
position. If all of the gravitational potential energy of the apple on the tree is transferred to the spring
when it is compressed, what is the spring constant of this spring?

2 m
A) 10 N/m
B) 40 N/m
