Alice and Bob had car trouble. Their car broke down and Bob could not restart it. Alice got out to push the car and after some time she asked Bob if he would
trade jobs with her for a while.
Bob answered, "It won't matter if I do. I took physics, and I know that no matter how hard I push on the car, it will push back on me just as hard so I won't
accomplish anything. That's Newton's Third Law and it is always true. It has been tested millions of times. It wouldn't matter if I pushed the car. I wouldn't be
able to push it anywhere."
Aside from the fact that his relationship with Alice is probably fınished, which of the following correctly explains a flaw in Bob's logic?
The third law says that the two forces he is talking about are only approximately equal.
The third law does not apply in this case because the car is on wheels.
O The two forces he is talking about are on two different objects.
Thw two forces will not be the same because the two masses are different.
The third law only…

You stop for a moment to add a bag of dog food to your cart.
With a force of 12.0 N, you now accelerate the cart from rest
through a distance of 2.29 m in 3.00 s. What was the mass of the
dog food?
