(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.
