Question

a block weighs 200 N and is being held against a door. The coefficient of static friction between the door and the block is 0.470. What is the minimum force applied?

Please show how you got it

Answer 1

friction=mu*Forcehorizonal

Now, I wonder what is the purpose of the block? To hold the door shut? or just keep the block from falling.

If this is a falling issue.

200=mu*force solve for force.
