The sun's mass is 1.99 x 10^30 kg, the earth's mass is 5.98 x 10^24 kg, and the moon's mass is 7.36 x 10^22 kg. The average distance between the moon and the earth is 3.82 x 10^8 m, and the average distance between the earth and the sun is 1.50 x 10^11 m. a. Using Newton's law of gravitation, find the average force exerted on the earth by the sun. b. Find the average force exerted on the earth by the moon. c. What is the ratio of the force exerted on the earth by the sun to that exerted by the moon? Will the moon have much of an impact on the earth's orbit around the sun? d. Using the distance between the earth and the sun as the average distance between the moon and the sun, find the average force exerted on the moon by the sun. ) Will the sun have much impact on the orbit of the moon around the earth?
A ship sets out to sail to a point 141km due north. An unexpected storm blows the ship to a point 138 km due east of its starting point. (a) How far (in km) and (b) in what direction (as an angle from due east, where north of east is a positive an..
