Homework Help Overview

The discussion revolves around calculating force components for a body moving diagonally under the influence of various forces, including gravitational force and a lateral wind force. The scenario involves a body with a specified mass, speed, and time of travel, prompting questions about the appropriate calculations and methods to determine the resultant forces.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants explore the relationship between mass, gravitational force, and the effects of lateral forces on the motion of the body. Questions arise regarding the use of trigonometric functions, the definition of "side effect," and the implications of the stated lack of acceleration. There is also a discussion about the need to calculate the distance traveled and the relevance of angles in the context of the problem.

Discussion Status

The discussion is active, with participants questioning the assumptions made about acceleration and the forces involved. Some guidance is offered regarding the use of Pythagorean theorem and the need to clarify the forces acting on the body. However, there is no explicit consensus on the correct approach or interpretation of the problem.

Contextual Notes

Participants note potential confusion regarding the definitions of forces and the conditions of the problem, such as the lack of acceleration and the effects of wind. There is also mention of needing to find the distance traveled, which adds complexity to the calculations being discussed.

Just a question about simple moving body exercise. With no acceleration.

Body moves with speed 15 m/s, time 12 seconds, mass 0.8 kg, and the force have a side effect 5 Newtons.

Firstly, F=mg, so 0,8*0,98.Then I calculated the actual moving direction's force by pythagoros, that's 0,95N.


Should i use cosinus or what ?

hi emutudeng! :smile:

i don't understand :redface:

you say there's no acceleration, but then you use g,

and what do you mean by "side effect"?

and what angle is there (for the cosine)?

what exactly is the body doing? :confused:
 
Lets say there is a body (0,8kg) moving in direct line for 12 seconds with balanced speed 15 m/s, but there is a wind blowing from a side with a force 0,5 N.

So the body is moving diagonally and I should get the diagonal with pytagoros. The thought that the angle is between the actual trajector and the first direct line, but maybe i don't even need it.

Edit: i need the distance
 
ah!

ok, then this is wrong …

F is the force, and that's already given, as 0.5 N

you need to find the acceleration, so use F = ma :wink:

then find the sideways distance moved, then use pythagoras :smile:
