What is the escape speed from a planet of mass M and radius R if M = 3.2 * 1023 kg and R = 2.4 * 106 m?
A)5.5 km/s
B)4.2 km/s
C)5.2 km/s
D)4.8 km/s
E)3.7 km/s

The escape speed is calculated using the formula v = sqrt(2GM/R). Plugging in the values G = 6.674 * 10^-11 m^3/kg/s^2, M = 3.2 * 10^23 kg, and R = 2.4 * 10^6 m, the escape speed is approximately 4.2 km/s.
