(1) A 4m ladder has mass m= 10 kg. We assume that its centre of mass is half-way along its length. The ladder is leaning against a wall at an angle of 30° from the vertical, as shown in the figure. Suppose that the wall is frictionless smooth and slippery), and that the coefficient of static friction between the feet of the ladder and the floor is H. =0.6. Take the acceleration due to gravity to be g=10m/s" directed vertically...

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. Part A Draw a free-body diagram of the crate. Part B 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...
