Solve the below problem:
Q: The value of the acceleration of gravity at any latitude f is given by g = 9.7087(1 + 0.0053 sin2 f) m/s2, where the effect of the rotation of tbhye earth as well as the fact that the earth is not spherical have been taken into account. Knowing that the mass of a gold bar has been officially designated as 2 kg, determine to four significant figures its mass in kilograms and its weight in newtons at a latitude of
(a) 0° ,
(b) 45° ,
(c) 60°.
