In this problem, we know both the magnitude and direction for each of the velocity and acceleration vectors for the center of mass G. We know that the unit tangent vector e t is in the same direction ...

We can't say because there is insufficient information. A direction is required before we can describe the force properly. Displacement is a distance and a direction, eg \(170m\) south. Velocity is a ...

In this paper, we shall construct explicitly irreducible relative invariants of two 2-simple prehomogeneous vector spaces. Together with a preprint by the same authors, this completes the list of all ...
