Asked by tt

Enrique is given information about a satellite orbiting Earth.

r = 3.8 × 108 m

T = 18 days

In order to calculate the tangential speed of the satellite, what should Enrique do first?

convert the radius to kilometers
convert the orbital period to seconds
find the square root of the radius
find the square root of the orbital period

Convert the orbital period to seconds.

Reason: tangential speed v = 2πr/T. r is given in meters, so T must be in seconds for v in m/s. 18 days = 18×24×3600 = 1,555,200 s. (If you continue: v ≈ 2π(3.8×10^8 m)/1.5552×10^6 s ≈ 1.54×10^3 m/s.)
