Please can someone help me, I am really confused. A create of mass 5kg lies on a rough horizontal floor. The coefficient of the friction between the floor and the crate is 0.45. A rope is attched to the box to pull the crate along the floor. How do you find out the magnitude of that the tension must exceed in order to move the box if the rope is 50 degrees abpve the horizontal. Thanks for all your help
