Homework Help Overview

The discussion revolves around determining the acceleration of a 7.00 kg sphere submerged in seawater at a depth of 1.20 km. The problem involves concepts from fluid mechanics and dynamics.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the calculation of forces acting on the sphere, including weight and buoyancy. There is an initial uncertainty about the mass of the sphere, which is clarified by another participant.

Discussion Status

The discussion is active, with participants exploring the necessary forces to determine acceleration. Some guidance has been offered regarding the calculation of weight and buoyancy forces, but no consensus or resolution has been reached yet.

Contextual Notes

Participants are working within the constraints of the problem, which includes the density of seawater and the dimensions of the sphere. There is an emphasis on understanding the forces involved without providing a direct solution.

A 7.00 kg sphere of radius 5.00 cm is at depth of 1.20 km in seawater that has density 1025 kg/m^3.What is the magnitude and direction of the spheres accelreation if its free to move?
i got to the part were i don't know what the mass of the sphere is help anyone please i tried f=ma no work

Um, isn't the mass of the sphere given, 7.00kg?
 
yes u are right thanks
 
Wasn't sure if you'd figured out your peoblem yet or not, but here goes...

Find your weight (mg) and bouyancy forces (related to the volume of sea water displaced (ie volume of sphere using radius)) and you should be able to get acceleration and direction from your resultant force.
