An object at rest will stay at rest unless acted on by an unbalanced force. In order for it to stay at rest, The friction and gravitational forces must be equal. I still don't see where I went wrong! And if the 123. N force is the minimum required to keep the object at rest, then how does a 100...
Homework Statement
A 5.00-kg block is held at rest against a vertical wall by a horizontal force of 100 N. (a) What is the frictional force exerted by the wall on the block? (b) What is the minimum horizontal force needed to prevent the block from falling if the static coefficient of friction...
