Question

You are forced to land on an unknown planet by equipment failure. You need to find the local acceleration due to gravity in order to plan your escape. You rig up a pendulum with a mass of 5 kg and a length of 3. and when you time What is the the period of the pendulum the local acceleration due to gravity in meters per sec squared? Your mass is 80 kilograms. How much do you weigh on this planet? How much did you weigh on Earth? g on Earth-10 m/see? , Period of a pendulumis: Tlength/g (hints: Put g on the left of the equation. How do you get rid of the radical sign?). Acceleration due to gravity Your weight on Earth

Explanation / Answer

Time period=2*pi*sqrt(l/g)

By putting data

1.52=2*pi*sqrt(3.25/g)

We got

g=55.25m/s^2

My weight on planet=80*55.25=4420N

My weight on earth=80*9.8=784N
