homework and exercises - Dog running after shepherd



Assume there is a dog A on a field and a sephard B. B moves on straight line with constant $v$ velocity. The dog A is running always towards B with also constant - magnitude `$u$ velocity.


If initially B's velocity vector is perpendicular to A's velocity vector, when will they meet?


Is it possible to solve the problem above without the use of calculus? How?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
