Answer 1

Dear Student,
Please try to post the picture so that we can help .

Diagram is given as attachment.
The diagram shows two dodge balls colliding. The red arrow shows the direction of force of the moving ball striking a stationary ball.
According o Newton's Third law of motion, For every action there is equal and opposite reaction.
Action=-reaction
So the Arrow which is opposite to  direction of force exerted by red ball   indicates the force exerted by stationary ball on red ball
