AI Thread Summary
The discussion centers on Newton's Third Law of Motion, specifically in the context of a tennis ball hitting a racket. The action and reaction forces are described as the ball pushing against the racket and the racket pushing back against the ball, with both forces being equal in magnitude. The confusion arises regarding why these forces do not cancel each other out; the clarification provided is that they act on different objects. The concept of inertia is mentioned, but the key point is that the forces do not cancel because they are not acting on the same object. Understanding this distinction is crucial for grasping the principles of action and reaction in physics.

Homework Statement


This question has three parts, and i think i have a and b down.

a) Describe the action/reaction of a tennis ball hitting a racket:

b) Are the magnitudes of the forces equal?

c)Why don't the forces cancel each other out upon contact?

Homework Equations




The Attempt at a Solution


a)I said the ball pushes against the racket, the racket pushes against the ball
b)Yes.
c)HERE IS WHERE I'm CONFUSED: My guess is because of inertia, but I'm not really sure what inertia is exactly, could someone tell me if I'm correct?

Each of the forces is exerted on a different object.
 
a)the ball pushes the racket & vice versa.
b)yes.
c)since the two force do not act on same object they do not cancel each other.
 
Oh yeah that makes sense, thanks physics geniuses!
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
