Which statement correctly characterizes the linear momentum p of a moving object?
(a) p equals the net force acting on the object multiplied by the time interval during which the force acts, so p points in the direction of the net force.
(b) p equals the object’s mass multiplied by its velocity and therefore points in the same direction as the velocity.
(c) p equals the object’s mass multiplied by its speed and therefore is a scalar quantity.
(d) p equals the object’s kinetic energy divided by its speed and therefore points in the same direction as the velocity.
