Solving a Buoyancy Problem: Determining the Weight of a Truck on a Ferry Boat

AI Thread Summary
To determine the weight of the truck on the ferry boat, the problem involves calculating the volume of water displaced when the boat sinks 4.00 cm. The dimensions of the ferry boat are 4.0 m wide and 6.0 m long, allowing for the calculation of the displaced water volume. Using the density of water, the weight of the displaced water equals the weight of the truck, leading to the conclusion that the truck weighs 960 kg. The approach involves applying the formula for density, where mass equals density times volume. The solution effectively illustrates the principles of buoyancy and displacement.

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 weight of the truck?


Homework Equations


\rho=m/v
and others


The Attempt at a Solution


none. My teacher gave my class chapter to read and complete on our own. I have no idea where to begin to start solving this problem.
 
Physics news on Phys.org
Water must be displaced to get the buoyancy to hold up the truck. The weight of the water displaced will be same as the weight of the truck.
 
do i use the P=m/v equation and solve for m?
i would use the density of water for P, and the volume of the water displaced for v, right? I think i understand.
would the answer be 960 kg?
 
That's it.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
