Having landed on a newly discovered planet, an astronaut sets up a simple pendulum of

length 1.51 m and finds that it makes 291 complete oscillations in 697 s. The amplitude of the oscillations is very small compared to the pendulumâ€™s length.

What is the gravitational acceleration on the surface of this planet?

Answer in units of m/s2

thanks!!!!
