In 2000, NASA placed a satellite in orbit around an asteroid. Consider a spherical asteroid with a mass of 1.50×1016 kg and a radius of 9.00 km .What is the speed of a satellite orbiting 4.60 km above the surface?

8.58 m/s.

Explanation:

Given,

Mass of the asteroid,M = 1.50 x 10¹⁶ Kg

radius = 9 Km

distance of the satellite, r = 4.60 Km

Speed of the satellite  = ?

R = 9 + 4.60 = 13.60 Km

Speed of the satellite rotating in orbit

G is gravitational constant

v = 8.58 m/s

Speed of the satellite is equal to 8.58 m/s.

this could be newton#'s law of cooling. the cooling curve is exponential
