Object A is traveling to the right at 5 cm/s. Object B is not moving (0 cm/s). They both have the same mass. When they collide . . .

• the forces will be different strengths and in the opposite direction

• the forces will be the same strength and in the opposite direction

• the forces will be the same strength in the same direction

• the forces will be different strengths in the same direction
