Astronauts on a distant planet set up a sithide perduhum of lergeth 120 m. The pentullum exeruites simple hamoric motion and makes 100 complete cscillations in 450 s. Whtat ls thle thasnitude of the anceleration due to gravity of this thater?
2.34(m)/(s^(n))2
93(m)/(s)62
4.12(m)/(s)*2
3.65(m)/(s^(12))
