    Calculate the force of ball on an incline leaning on a wall

    Ok so I think I've got then... The vertical component of the reaction force of the plane = the total gravitational force (i.e 9.81 x 1kg), so the horizontal component of reaction force of the plane would be 9.81*tan alpha Newtons or Fw= tan(alpha) kg wt Thanks for your help!

    Calculate the force of ball on an incline leaning on a wall

    Of course I do; check the diagram. I am looking for some insight into where the tan(alpha) comes from. I've provided all the information given in the question, I need to get some sense of how to proceed with a solution, and would appreciate constructive advice.

    Calculate the force of ball on an incline leaning on a wall

    As far as I can tell, I don't think it can. "both surfaces have negligible friction"

    Calculate the force of ball on an incline leaning on a wall

    I imagine the vertical wall can counteract the force

    Calculate the force of ball on an incline leaning on a wall

    Hi all, I'm working on a problem from the Feynman exercise book, and have been racking my brains for an answer, so would really appreciate some help here. The problem seems simple enough: A ball with a 3cm radius, weighing 1kg rests on an inclined plane (angle alpha) and also touches a...
