Homework Help Overview

The discussion revolves around a set of physics problems involving kinematics, specifically focusing on motion equations, acceleration, and velocity. The original poster presents four questions related to the motion of a scuba diver, a car, and a lab cart, seeking assistance in determining the appropriate equations and methods to solve them.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the use of Newton's equations of motion and express uncertainty about which equations to apply to each problem. There are attempts to break down the problems into variables and identify knowns and unknowns. Some participants question the initial conditions, such as the initial velocity of the cork and the diver.

Discussion Status

Several participants have provided guidance on identifying relevant equations and breaking down the problems. There is ongoing exploration of different interpretations of the initial conditions, particularly regarding the cork's motion and the diver's depth. Some participants express confusion about specific calculations and seek clarification on the application of equations.

Contextual Notes

The original poster mentions having missed school due to illness, which may contribute to their uncertainty. There is a general acknowledgment of the need to clarify assumptions and initial conditions before proceeding with calculations.

See my previous post. The formulas and explanation are given.

V1 ~ 0.23 m/s, and acceleration a ~ 0.116 m/s2.


One needs to understand how to apply the formulas, not just how to plug numbers into equations.

The real world does not have answers in the back of a book. The real world requires hard work and effort.

Well, thank you sir.

I love you.

Something tells me you will be seeing me tomorrow.
