Homework Help Overview

The problem involves an object of mass m moving at a constant velocity v that begins to ascend an incline of mass m2 at an angle theta. The objective is to determine the velocities of both the object and the incline when the object reaches its highest point, as well as the height of that point.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the nature of the problem, considering the incline's ability to move and whether this scenario resembles an inelastic collision. There are questions about the completeness of the problem statement, particularly regarding the absence of friction.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem. Some suggest considering both frictionless and friction-influenced scenarios, while others seek clarification on the problem's details.

Contextual Notes

There is uncertainty regarding whether friction is a factor in the problem, as it has not been explicitly mentioned in the original statement.

Homework Statement


There is an object with mass m that travels at constant velocity v. Then it starts to travel up a an incline of mass m2 and angle theta.

Find the velocities of both when the block reaches its highest point and what is this highest point.

Homework Equations



Energy/momentum equations

The Attempt at a Solution


This would be a standard question if it weren't for the fact that the incline can move. So I am assuming that the object/incline will be one unit and therefore it'll be like an inelastic collision, but I am not sure.

Hi bob123ed. http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif

Does the textbook give the answers?

No, I do not have an answer for the question.

Is that the entire question, word for word? Nothing about friction?

Technically, yes, but sometimes problem setters intend a smooth transition and fail to mention that. Maybe attempt both cases.
