Question

please finish both of the questions and the subsections and keep the steps neat so I can understand what's going on. thank u

A person holds a ball in her hand. (a) Identify all the external forces acting on the ball and the Newton's third-law reaction force to each one. (Select all that apply.) The force due to gravity of the earth pulling down on the hand; the reaction force is the force due to gravity of the hand pulling up on the earth The force of the hand pushing up on the ball; the reaction force is ball pushing down on the hand The force due to gravity of the earth pulling down on the ball; the reaction force is the force due to gravity of the ball pulling up on the earth. No forces act on the ball (b) If the ball is dropped, what force is exerted on it while it is falling? Identify the reaction force in this case. (Ignore air resistance.) O No forces act on the ball while it is in free fall. O The gravity due to the earth; the reaction force is the gravity due to the ball pulling on the earth O The force of the hand pushing up on the bali:,the reaction force is bl puahing down onthe hand O The force due to gravity of the earth pulling down on the hand; the reaction force is the force due to gravity of the hand pulling up on the earth. 24. 8 5 co 002 My Notes Ask Your if a car is traveling westward with a constant speed of 26.1 m/s, what is the resultant force acting on it? Type here to search 201

Explanation / Answer

According to Newton third law, every action there is an equivalent and opssite reaction

The Earth attracts the ball downward with the force of gravity is the action force and the ball attracts the Earth upward with theforce of gravity is the reaction force

The force due to gravity of the earth pulling down on the ball; the reaction force is the force due to gravity of the ball pulling up on the earth.

The force of the hand pushing up on the ball; the reaction force is ball pushing down on the hand.

so the above two options are correct answers

(b)

The hand pushes up on the ball is the action force and the ball pushes down on the hand is the reaction force

so, The gravity due to the earth; the reaction force is the gravity due to the ball pulling on the earth is the correct answer
