Speed = 22.8m/min
= 22.8 / 60
=0.38m/s
time = distance/ speed
= 467/0.38
= 1252.63s
Given: Mass of earth Me = 5.98 x 10²⁴ Kg
Radius of satellite - radius of the earth
r = 13,594 Km - 6,380 Km = 7,214 Km convert to meter "m"
r = 7,214,000 m
G = 6.67 x 10⁻¹¹ N.m²/Kg²
Required: What is the period T = ?
Formula: F = ma; F = GMeMsat/r² Centripetal acceleration ac = V²/r
but V = 2πr/T
equate T from all equation.
F = ma
GMeMsat/r² = Msat4π²/rT²
GMe = 4π²r³/T²
T² = 4π²r³/GMe
T² = 39.48(7,214,000 m)³/(6.67 x 10⁻¹¹ N.m²/Kg²)(5.98 x 10²⁴ Kg)
T² = 1.48 x 10²² m³/3.99 x 10¹⁴ m³/s²
T² = 37,092,731.83 s²
T = 6,090.38 seconds or 1.7 Hr
