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
from right to left, making a 180° reversal
at an angle of 90° to the initial direction of motion
at an angle of 270° to the initial direction of motion
