Imagine you are an astronaut who has landed on another planet and wants to determine the freefall acceleration on that planet. In one of the experiments you decide to conduct, you use a pendulum 0.47 m long and find that the period of oscillation for this pendulum is 1.43 s. What is the acceleration due to gravity on that planet? (Enter the magnitude only.)
I know the formula to use is
T=2pi(L/g)^0.5(g) but I keep getting a wrong answer

t^2=2x3.14x0.47/a
Or, a=6.28x0.47/1.43^2=0.43 m/sec^2
