The freefall 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

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)
(k is the spring constant and you can guess what m is)
Use these formulas to solve your problems.
