A toy chest and its contents have a combined weight of W = 220 N. The coefficient of static friction between toy chest and floor μs is 0.460. The child in the figure attempts to move the chest across the floor by pulling on an attached rope. (a) If θ is 46.0°, what is the magnitude of the force Upper F overBar that the child must exert on the rope to put the chest on the verge of moving? Determine (b) the value of θ for which F is a minimum and (c) that minimum magnitude.

    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 μs between the crate and the floor be...

    1. A block with weight W = 30 N is on a flat horizontal surface. You pull to the right with a force F = 16 N. There is gravity present and the coefficient of friction is static = 0.4 and kinetic - 0.25. You are also pulling straight up with an applied force of 12 N. Now what are: The normal force N-_ the frictional force f- the net force on the block Foot and acceleration a = 2....
