Point A moves uniformly with velocity `nu` so that the vector `v` is continually "aimed" at point B which in its turn moves rectilinearly and uniformly with velocity `upsilon lt nu`. At the initial moment of time `v_|_u` and the points are separated by a distance `l`. How soon will the points converge?

Two points of a rod move with velocity 3 v and v perpendicular to the rod and in the same direction. Separated by a distance r . Then the angular velocity of the rod is :

A point moves rectilinearly with deceleration which depends on the velocity v of the particle as a = k sqrtv , where is apositive constant. At the initial moments the velocity of the point is equal to v_(0) . What distance will it cover before it stops, and what time it will take to cover that distance.

A point moves rectilinearly with deceleration whose modulus depends on the velocity v of the particle as alpha=ksqrtv , where k is a positive constant. At the initial moment the velocity of the point is equal to V_0 . What distance will it take to cover that distance?

A point moves rectilinearly with deceleration whose modulus depends on the velocity v of the particle as w=asqrtv , where a is a positive constant. At the initial moment the velocity of the point is equal to v_0 . What distance will it traverse before it stops? What time will it take to cover that distance?
