Question
a) Calculate the magnitude of the gravitationalforce exerted on a 441-kg satellite that is a distance of 2.17times earth radii from the center of the earth.(b) What is the magnitude of the gravitationalforce exerted on the earth by the satellite? (c)Determine the magnitude of the satellite's acceleration.(d) What is the magnitude of the earth'sacceleration?i already have answers a-c i just need answer for letter (d) andplease make sure its only 3 significant number for the answer.Alsoi cant have the answer to the power of anything. Thanks
Explanation / Answer
(a)the magnitude of the gravitational force exerted on a441-kg satellite that is a distance of 2.17 times earth radii fromthe center of the earth. radius of the Earth =6380 km mass of the Earth =6*1024 kg F= GMm/(2.17*R)2 = 921 N(b)the magnitude of the gravitational forceexerted on the earth by the satellite
from the 3rd law of Newton => = 921N (c) the magnitude ofthe satellite's acceleration.
a=F/m =921/441=2.09 m/s2
(d) the magnitude of the earth'sacceleration a=F/M=921/[6x1024]=1.54x10-22m/s2
