The acceleration due to gravity at the North Pole of Neptune is approximately 11.2m/s^2. Neptune has a mass 1.02 x 10^26 kg and radius 2.46x10^4 km and rotates once around its axis in a time of about 16h.

A) what is the gravitational force on a 4.40 kg object at the North Pole of Neptune!?

B) what is the apparent weight of this object at Neptune equator!? ( note that Neptunes surface is gaseous not solid so it's impossible to stand on it!?

(A) Calculate the acceleration of gravity, gC, on Ceres Apply the kinematics displacement equation to the falling rock. (1) Δx = 1/2at2 + v0t Substitute Δx = -10.0 m, v0 = 0, a = -gC, and t = 8.06 s, and solve for the gravitational acceleration on Ceres, gC. -10.0 m = -1/2gC(8.06 s)2 → gC = 0.308 m/s2 (B) Find the mass of Ceres. Equate the weight of the rock on Ceres to the gravitational force acting on the...

Large stars can explode as they finish burning their nuclear fuel, causing a supernova. The explosion blows away the outer layers of the star. According to Newton’s third law, the forces that push the outer layers away have reaction forces that are inwardly directed on the core of the star. These forces compress the core and can cause the core to undergo a gravitational collapse. The gravitational forces keep pulling all the matter together tighter and tighter, crushing atoms out...
