Having landed on a newly discovered planet, an astronaut sets up a simple pendulum of length 1.25 m and finds that it makes 419
Zina [86]

Answer:

g=2406.8m/s^{2}

Explanation:

firstly we have to find the frequency and then the angular frequency.

The frequency will be:

   f=\frac{419}{60} \\f=6.98Hz

The angular frequency is:

ω=2\pi f

ω=2*\frac{22}{7} *6.98

ω=43.88rad /sec

Now we can apply simple pendulum relationship

ω=\sqrt{\frac{g}{l} }

make g the subject of the formula

g=w^{2} l\\g=43.88^{2} *1.25\\g=2406.8m/s^{2}
