What is the mass of the planet

Reference no: EM13661522

An astronaut arrives at a new planet, and gets out his simple device to decide the gravitational acceleration there. Prior to this arrival, he noted that the radius of the planet was 7040 km. If his 0.400-m-long pendulum has a period of 1.0 s, what is the mass of the planet?
