Problem

A 2.0\,kg brick rests on Earth’s surface. Taking the acceleration due to gravity to be 9.8\,m/s2^2 and Earth’s mass to be 6.0×10246.0\times10^{24}\,kg, determine the magnitude of Earth’s acceleration toward the brick. (a) 1.6×10−24 m/s21.6\times10^{-24}\,\text{m/s}^2 (b) 3×10−23 m/s23\times10^{-23}\,\text{m/s}^2 (c) 3×10−24 m/s23\times10^{-24}\,\text{m/s}^2 (d) 3×10−25 m/s23\times10^{-25}\,\text{m/s}^2
