(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

**drwls**, Sunday, December 5, 2010 at 5:00pmThe 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.
