The discussion revolves around determining the magnitude of acceleration of a block on a frictionless inclined plane, given its mass and the angle of the incline. Participants are exploring the forces acting on the block and how to apply Newton's second law in this context.
The discussion is ongoing, with participants providing guidance on identifying forces and calculating net force. There is a request for clarification on calculations, and some participants are encouraged to share their work to identify errors. Multiple interpretations of the forces involved are being explored.
There is mention of needing more information to resolve discrepancies in calculations, and participants are encouraged to provide the original problem statement for further assistance.
The normal force is one of the forces acting on the block, but it does not equal the weight.queenspublic said:What forces act on the block?
Would that be normal force which is the weight? (40.67? Am I right?)
No. If the weight were equal and opposite to the normal force, the block would just sit there.queenspublic said:My diagram has the normal force that keeps it up. The weight force pulling it down which opposite of normal force.
Tension from what?And tension moving it forward.
OK, that's the net force acting on the block.queenspublic said:Okay...so I used the m*g*sin30
Wrong answer for what?m = 4.15
g = 9.8
and I still got the wrong answer.
If you want to find the acceleration, divide the net force by the mass. (F = ma → a = F/m.)then i divided by mass again and got wrong answer again.
