(a)
Find the magnitude of the gravitational force (in N) between a planet with mass 7.00 ✕ 1024 kg and its moon, with mass 2.75 ✕ 1022 kg, if the average distance between their centers is 2.50 ✕ 108 m.
N
(b)
What is the moon's acceleration (in m/s2) toward the planet? (Enter the magnitude.)
m/s2
(c)
What is the planet's acceleration (in m/s2) toward the moon? (Enter the magnitude.)
m/s2
Because the Earth rotates about its axis, a point on the equator experiences a centripetal acceleration of 0.033 7 m/s2, whereas a point at the poles experiences no centripetal acceleration. If a person at the equator has a mass of 75.0 kg, calculate (a) the gravitational force (true weight) on the person and (b) the normal force (apparent weight) on the person. (c) Which force is greater? Assume the Earth is a uniform sphere and take g = 9.800 m/s2.
a)find the magnitude of the gravitational force (in N) between a planet with mass 9.00 ✕ 1024 kg and its moon, with mass 2.20 ✕ 1022 kg, if the average distance between their centers is 2.20 ✕ 108 m.

- For this problem, assume that the earth is a perfect sphere. Also, assume that if your mass is m, then the earth exerts a gravitational force on you of magnitude mg, where g = 9.8 m/s2 at all points of the earth's surface. a) Your mass is m = will the scale read? (Thanks to the Third Law, this is the same as asking for the normal force exerted on you by the scale.) b) Next you go to the Equator and stand on a scale. What does it read? The radius of the earth is 6.4 × 106 m. c) Suppose the earth were rotating so quickly that objects became “weightless" at the equator. How long would the day be? 50 kg.
