A steel ball of mass 50 g is rolled from the left toward a ball of lead of mass 500 g. The steel ball is traveling with a velocity of 5 m/s. If no external forces act on either of the interacting bodies, then what will be the direction of the momentum of the steel ball after the head-on collision? A) from left to right as it started off
B) from right to left, making a 180° reversal
C) at an angle of 90° to the initial direction of motion
D) at an angle of 270° to the initial direction of motion
