Oh, I guess that is rather large...
But yes, you are right, atmospheric pressure is the pressure at the surface, but the problem states to not take that into account.

A swimming pool has the dimensions 24 m multiplied by 9.0 m multiplied by 2.5 m.
(a) When it is filled with water, what is the force (resulting from the water alone) on the bottom, on the short sides, and on the long sides?

A bowler throws a bowling ball of radius R = 11 cm down the lane with initial speed v0 = 8.5 m/s. The ball is thrown in such a way that it skids for a certain distance before it starts to roll. It is not rotating at all when it first hits the lane, its motion being pure...
Well the normal force is at the edge of the base.
The center of mass, at the point where the it aligns with the base, is when it starts to tip, based on what you said.
But what is the proof for that? The sum of all forces in the y-direction at this point would be past 0 because the...
Well, when the tower is about to fall over, the normal force acts in the positive y-direction at the base of the tower and the weight acts in the negative y-direction at the tower's center of mass.
Homework Statement
The leaning Tower of Pisa (Fig. 9-47) is 55 m high and 7.0 m in diameter. The top of the tower is displaced 4.5 m from the vertical. Treat the tower as a uniform, circular cylinder.
(a) What additional displacement, measured at the top, will bring the tower to the...
\frac{v}{c} = \frac{pc}{E}
\frac{v}{c} = \frac{mv\gamma}{mc^2\gamma}
in which case becomes
\frac{1}{} = \frac{1}{c}
i realized originally i made a mistake but now i got something different...
So then what is the p in the equation?
And I did the algebra, and tried to solve for v, but i keep running into trouble.
I keep getting a value of 0 whenever I use the algebra...
