AI Thread Summary
To calculate the combined weight of the truck and ferry boat, the buoyant force must be considered, which equals the weight of the displaced water when the truck is on the ferry. The ferry's dimensions allow for the calculation of the volume of water displaced when it sinks 4.00 cm. Users are encouraged to demonstrate their understanding by showing initial attempts at the problem, as this forum prioritizes learning through engagement. Providing relevant equations and explaining their connection to the problem is essential for receiving assistance. Overall, active participation and effort in problem-solving are necessary for effective help in this forum.

Homework Statement



A ferry boat is 4.0 m wide and 6.0 m long. When a truck pulls onto it, the boat sinks 4.00 cm in the water. What is the combined weight of the truck and ferry?

Homework Equations



Buoyant force = Weight of the floating object

The Attempt at a Solution



How would I find the weight when I don't know the mass of either object? I don't know what equation I would use or how to get started on the problem...

Welcome to PF bor33d. This is a great place to get homework help but you have to understand that we have rules here. You have not shown ANY attempt on the problems you have posted in this forum. (I have seen your other threads.) The rules are that you must show some work before you get help here. I know you are not far enough along to do any calculations in these problems, and that is fine, but you still need to show some effort. For instance, in all of your problems you have posted formulas that do apply the the problem. Why did you decide to post them? How do they relate what your given and what you need to find?Sorry, but if I just told you what equations to use, you wouldn't get anything out of this thread or your others.

So show me some of your thoughts on this problem.
 

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...
