Compare the binding energy of a body at rest on the surface of the earth with the binding energy of a body of same mass at rest on the surface of the moon. (g = 9.8 m/s^2 , Radius of the earth = 6400 km, Radius of the moon= 1747 km)

An oscillator consists of a block of mass 512 g connected to a spring. When set into oscillation with amplitude 34.7 cm, it is observed to repeat its motion every 0.484 s. Find (a) the period, (b) the frequency, (c) the angular frequency, (d) the force constant, (e) the maximum speed, and ( f ) the maximum force exerted on the block.
