peg 30° A uniform ladder is 10m long and weighs 400 N. It rests with its upper end against a frictionless vertical wall. Its lower end rests on the ground and is prevented from slipping by a peg driven into the ground. The ladder makes a 30? angle with the horizontal. The magnitude of the force exerted on the peg by the ladder is: A. zero B. 200N C. 400N D. 470N E. 670N

A body moving in a circle with a constant seed is in rotational equilibrium.

A 14.0 uniform ladder Leghins 510N rests against a frictionless wall. The ladder makes 55.0 angle without the horizontal. It the ladder is just on the verge of slipping when the firefighther Weighing 757N is 9.30m from the bottom, what is the coetticient of static Friction between ladder and ground?

In the figure, a 10.0-m long bar is attached by a frictionless hinge to a wall and held horizont by a rope that makes an angle 0 of 53° with the bar. The bar is uniform and weighs 39.9 N. H far from the hinge should a 10.0-kg mass be suspended for the tension T in the rope to be 125 N? ... 10 kg 10 m A) 5.5 m from the hinge B) 6.4 m from the hinge C) 8.15 m from the hinge D) 7.7 m from the hinge

A uniform stick AB can be balanced on a knife edge 10 cm from one end when a weight of 200N is hung from that end. When the knife edge is removed 5cm further from that end, the 200 N weight has to be moved to a point 8.75 cm from the knife edge to obtain a balance. Find the length of the stick and it's weight.

A uniform ladder 8m long and weighing 350N restsagainst a smooth vertical wallat an angle of 30 ̊ to the wall. A 700 N man stands 6m up from the bottom of the ladder. Find the horizontal force necessary at thebase to keep the ladder from skipping?
