An astronaut constructs a pendulum with a length of 1 meter on a new planet. If the period is 3.9 second, what is the acceleration due to gravity?
Can someone help me with formulas to determine this?

  1. period=2PI*sqrt(l/g)
    3.9=2PI*sqrt(1/g)

    square both sides.
    3.9^2/(2PI)^2=1/g

    g=(2pi/3.9)^2
