Physics homework help, how to set up problem

AI Thread Summary
To solve the problem of a bullet embedding in wood, first determine the bullet's deceleration using the equation Vf^2 = Vo^2 + 2a(delta X). Given the bullet's initial velocity (487 m/s), final velocity (0 m/s), and distance traveled (0.55 m), calculate the acceleration. Once the acceleration is found, apply Newton's second law (F = ma) to find the force exerted by the wood on the bullet. This approach will provide the necessary steps to solve the physics problem effectively. Understanding the relationship between acceleration, mass, and force is crucial for arriving at the correct answer.

Homework Statement



A bullet of mass 0.0019 kg moving at 487 m/s embeds itself in a large fixed piece of wood and travels 0.55 m before coming to rest. Assume that the deceleration of the bullet is constant.

What force is exerted by the wood on the bullet?

Homework Equations



I think...Vf^2=Vo^2 + 2a(delta X)

The Attempt at a Solution



I don't even know how to set this problem up. I am guessing I am looking for the acceleration?
Much help appreciated.

Welcome to PF.

Yes, you can find the acceleration from that.

If you have the deceleration and you have the mass ... hmmm. Any ideas about what the force is?
 
not really...Am I suppose to find the deceleration of the bullet first and after getting that. I should be able to find N?
 
You can find 'a' from your equation, right? F=ma, also right? Can't you find force?
 

Thread 'Rolling without slipping on a curved surface'

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 .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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...
