2. You, a person with mass 75 kg, are on a the surface of recently discovered Planet Q. You construct a pendulum using a uniform solid disk (COM at the center) with radius 0.25 m and mass 2 kg: Ensuring that 90 is very small, you let the pendulum oscillate and measure that its total period is T = 1.5 s. Satellite data informs you that Planet Q has a radius of 8.3 x 108 m, and completes one full rotation around its axis in 3.0 x 105 s. (20 points) (a) If you stood on a scale Planet Q's surface, what would it read (in newtons)? (b) \"That is Planet Q's gravitational acceleration
