Question

write a 1, 2 or 3 for each of the following to indicate whether its newtons 1st, 2nd or 3rd law. 1. a climber pulls down on a rope causing his body to lift upward and rise along the rope. 2. force = mass x acceleration 3. two bumper cars collide into each other and each car jolts backwards

Explanation:

Step1: Identify Newton's 1st law

Newton's 1st law is about an object at rest staying at rest and an object in motion staying in motion with a constant velocity unless acted upon by an external force. The climber pulling down on the rope to lift himself does not relate to this law.

Step2: Identify Newton's 2nd law

Newton's 2nd law is \(F = ma\) (Force = Mass x Acceleration). The statement "Force = Mass x Acceleration" directly represents Newton's 2nd law.

Step3: Identify Newton's 3rd law

Newton's 3rd law states that for every action, there is an equal and opposite reaction. When two bumper - cars collide, the force exerted by one car on the other is met with an equal and opposite force, which is an example of Newton's 3rd law.

Answer:

1. 3
2. 2
3. 3
