Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Question

4. Car crash
A race-car driver crashes into a racetrack wall at an angle of 30 deg, with a speed of 70 m/s. Just after the collision,
she and the wreck move away from the wall at 50 m/s at an angle of 10 deg to the wall. If her mass is 70 kg then
what impulse does she experience?
