A 60 kg60\ \text{kg} astronaut is on Earth's surface. Using ME=6.0×1024 kgM_E = 6.0 \times 10^{24}\ \text{kg}, RE=6.4×106 mR_E = 6.4 \times 10^{6}\ \text{m}, and G=6.67×10−11 N⋅m2/kg2G = 6.67 \times 10^{-11}\ \text{N}\cdot\text{m}^2/\text{kg}^2, what is the gravitational force on the astronaut according to F=GMEmRE2F = G\dfrac{M_E m}{R_E^2}?
