The free-fall acceleration on Mars is 3.7 m/s2.

(a) What length pendulum has a period of 4 s on the earth?

cm

What length pendulum would have a 4 s period on Mars?

cm

(b) A mass is suspended from a spring with force constant 10 N/m. Find the mass suspended from this spring that would result in a 4 s period on Earth and on Mars.

Earth kg

Mars kg

I know the formulas, but for some reason I'm not getting it. How do I solve for L? Is it 2*pi*2*g? I'm confused.

The period of a pendulum is

2*pi*sqrt(L/g)

The period of a spring/mass system is

P = 2*pi*sqrt(m/k)
