Question

A polo player hits a ball with a mass of 0.42 kg with a force of 7.35 Newtons.

How does the force the polo player's mallet exerted on the ball compare to the force the ball exerted on the mallet?

Answer 1

A.
The force of the mallet on the ball is equal in magnitude and in the same direction to the force the ball exerted on the mallet.

B.
The force of the mallet on the ball is equal in magnitude and opposite in direction to the force the ball exerted on the mallet.

C.
The force of the mallet on the ball is greater in magnitude and opposite in direction to the force the ball exerted on the mallet.

D.
The force of the on the mallet is less in magnitude and opposite in direction to the force the ball exerted on the mallet.

Answer 4

Let me help!

Answer 5

Newtons third law: When two bodies collide, the force that one body exerts on the other is the same but in opposite direction that the other body exerts on the first. Therefore answer is B.

Thank you @Hoslos . Would you mind helping me with a few more?

Answer 7

or maybe @MrNood could help

Answer 8

No problem.

Answer 9

Amy gets up from her seat on the train to move closer to the front of the train. Just as she begins to walk toward the front, the train stops at a station.

Which of Newton's laws explains what happened to Amy?



A.
While Amy was walking, she was in motion due to the force of repulsion. When the train stopped, she was catapulted forward due to the train's stronger force of attraction. This is an application of Newton's Law of Universal Gravitation.

B.
While Amy was walking, her body was in motion, but when the train stopped, she experienced an unbalanced force and continued to move forward due to inertia. This is an application of Newton's First Law of Motion.

C.
While Amy was walking, her body was in motion, but as the train stopped, it exerted a force on Amy opposite to the direction she was walking and caused her to also stop. This is an application of Newton's Third Law of Motion.

D.
While Amy was walking, her body was in motion, but when the train stopped, an unbalanced force accelerated her body backward. This is an application of Newton's Second Law of Motion

I think it's A @Hoslos

Answer 10

What do you think?

Answer 11

I do ot think A is it, because it is about attraction of bodies due to gravity. For me, the answer should be as similar as this : she was in motion, bht when the train stopped, a backward force was exerted on her and her foot did the same in the opposite direction and eventually stopped.

Answer 12

So then it would be D?

Answer 13

So I would go for b, because it is about inertia and the example of when the car stops while you are sitting and when you are projected forwards is perfectly an example of application of inertia and this scenario looks the same to me.

Answer 14

I have just a few more if you wouldn't mind

Answer 15

I am okay. Just spit as much as you can.

Answer 16

@Hoslos
During a golf game, the ball is hit forward with 500 N of force using a golf club. According to Newton's Third Law of Motion, what is the force of the golf ball on the club?

A.
To determine the force on the golf ball, the force of 500 N by the golf club must be multiplied by gravity to get 4900 N.

B.
The golf club exerted an attractive force of 500 N on the golf ball, so the golf ball exerted a repulsive force of 500 N on the golf club.

C.
The golf club exerted a forward force of 500 N on the golf ball, so the golf ball exerted a backward force of 500 N on the golf club.

D.
The golf club exerted a forward force of 500 N on the golf ball. This activated a 500 N force of inertia from the golf ball to the golf club.

Answer 17

I think that this one is D

Answer 18

Your answer was very close. THEY TRicked you to see if you know the law well polished. THE LAW States that during a collision, when two bodies collide, the first one exerts a force on a second in a given direction, then the second exerts the same force on the first but in the opposite direction. Therefore answer is C.
