Problem

At an instant of time tt, a point object of mass mm moves with velocity v⃗\vec{v}, has acceleration aa, and is at position (x,y)(x,y). In what direction must the linear momentum of the object be directed at this instant? (A) Along the direction of the velocity of the mass (B) Along the direction of the net force acting on the mass (C) Along the direction of the vector from the origin (0,0)(0,0) to (x,y)(x,y) (D) Along the direction of the acceleration of the mass (E) Along the direction perpendicular to the object's acceleration
