You are trying to drag a heavy sleeper-sofa across your floor. The sofa has a mass of 150 kg and the coefficient of static friction between the couch and the floor is 1.08. Being a bright physics student, you realize that you can make this easier by pulling upwards and forwards at the same time rather that just pulling the sofa forwards. If you pull on the sofa at an angle 32? above the horizontal how much force does it...

Suppose you have to move a heavy crate of weight 875 N by sliding it along a horizontal concrete floor. You push the crate to the right with a horizontal force of magnitude 300 N, but friction prevents the crate from sliding. What is the magnitude Fp of the minimum force you need to exert on the crate to make it start sliding along the floor? Let the coefficient of static friction ?s between the crate and the floor be...
