If I understand your question, the velocity at (r,theta) is the vector sum of C and Ve at an angle theta. I know some calculus, integral and differential, but I just can't figure how to approach this problem, and I may not have enough knowledge to solve it even then.

By overright I mean at an angle from the deviated path or undeviated path to the center of M is such that their separation is the smallest it can be.

From the center. I cannot get anywhere with this problem

Can anyone solve this puzzle for me - a mass m in space with a constant velocity C heads toward a circular mass M such that if not disturbed it would pass by M at a distance of 2 of M's radiuses. However, the mass m experiences a second velocity Ve towards the center of M; the magnitude of this...

Thanks guys for taking the time to reply.

Tks. I understand what you're saying. I was asking a question beyond that. Imagine a mass unmoving in space. Unless it is held there by some force, why should a force be needed to move it? The math of inertia just describes, doesn't explain. Is the mass trapped in spacetime, which exerts a...

Hi: Will someone please answer this question: How does relativity explain inertia. What resists accelerational force; if there were nothing resisting the motivating force, why would a force be needed at all to set it in motion. Tks

Hi Ben. Tks for replying. Is the mass expansion and length contraction real then. I thought it was, from the observer's viewpoint. And what is more dense than a neutron?

That is extremely interesting to me, but I am not surprised by it. My own thoughts have led me to this conclusion (that of pancaking mass) which would max out at C

Thanks Ben. How then does the mass increase without the perpendicular radius increasing? I am assuming the neutron is the most dense unit of mass possible.

Thanks guys. Taking the case of a neutron moving with velocity v, would its radius in the direction of v shorten while its radius perpendicular to v increases? It seems if this is so, then the neutron would assume an ellipsoid shape, more specifically an oblate spheroid shape, until it would...

Hi: When a mass is accelerated, what happens to its length and volume? I know that when the acceleration ends, its length is governed by the equation l = l0 x sqrt (1 - v^2/C^2), but what about during the acceleration?

**!xxx Trajectory in a gravitational field Assume an object comes from infinity and passes by the sun at 2 solar radiuses from its center. Can you derive an equation describing the objects path using only escape velocities and C??

[FONT="Arial Narrow"]:smile:Hi I have been wrestling with this situation for a while, trying to derive an equation for it...A sphere is placed in a fluid of viscosity n and density p, outside any gravity. The sphere is instantly beamed out (perhaps by Capt Kirk?). At what volume rate will the...
