The answer to this is up (d).
But why?
Is it because centripetal acceleration is pointing to the center of the pivot?
I believe this is correct.Is it because centripetal acceleration is pointing to the center of the pivot?

In regards to how you should go about finding the gravitational acceleration you would feel on Jupiter, keep in mind that you are supposed to be finding acceleration. You look like you were solving for the force Jupiter will exert on an object, not the acceleration of gravity on Jupiter. This is a problem because the force that Jupiter will exert on an object depends on the mass of the object. It is true that
Fg = G Mm/r2
What else is Fg equal to? Could you use that relationship to find the acceleration on Jupiter?
Chestermiller said:Why did you insert gJupiter in the right hand side of the equation? G is a universal constant, and not related specifically to Jupiter. And where did the 9.81 come from? We are talking about Jupiter, not earth. In you most recent post, m is equal to m2, and g is what you are solving for; m2 is the mass of Jupiter.
riseofphoenix said:So,
mg = (6.67 x 10-11)m1(1.9 x 1027)/71.4922
(1.9 x 1027)g = (6.67 x 10-11)m1(1.9 x 1027)/71.4922
What about m1??
m = m2 = your mass
Chestermiller said:I'm sorry. I made a typo in my previous reply. Please excuse me. It should have read:
m = m2 = your mass
m1 = mass of Jupiter
This question is asking about the acceleration of a mass at the bottom of its swing, which is a common concept in physics. The answer to this question depends on a few factors such as the mass of the object, the length of the swing, and the force acting on the object. In general, the total acceleration at the bottom of a swing is equal to the acceleration due to gravity (9.8 m/s²) plus any additional acceleration caused by other forces.
The total acceleration at the bottom of the swing can be calculated using the formula a = g + a₂, where "g" is the acceleration due to gravity and "a₂" is any additional acceleration caused by other forces. This formula takes into account the fact that the direction of acceleration changes at the bottom of the swing, thus the total acceleration includes both the downward acceleration due to gravity and any upward acceleration caused by other forces.
Other forces that can affect the total acceleration at the bottom of the swing include air resistance, friction, and tension in the swing's support structure. These forces can either add to or subtract from the acceleration due to gravity, resulting in a different total acceleration at the bottom of the swing.
The total acceleration at the bottom of the swing will change as the mass swings back and forth due to the changing direction of acceleration. At the lowest point of the swing, the acceleration will be at its highest point, while at the highest point of the swing, the acceleration will be at its lowest point. This is because at the bottom of the swing, the acceleration is directed downwards, while at the top of the swing, the acceleration is directed upwards.
There is a direct relationship between the length of the swing and the total acceleration at the bottom. As the length of the swing increases, the total acceleration at the bottom will also increase. This is because a longer swing allows for a greater distance for the mass to accelerate, resulting in a higher total acceleration at the bottom. Similarly, a shorter swing will result in a lower total acceleration at the bottom.
