If the spring is more stiff what happens to the spring constant
It goes up.
k becomes greater in value if the spring is more stiff.

How could you use the following equation to make the perfect jumping frog
F = -kx
make the spring more stiff so that k increases, and make the spring taller so that it has more displacement.
