Suppose you use an ideal pulley of the type shown in Figure 5.18(b) and find it necessary to exert a force of 340 N to support a load. What is the load's mass?  kg What force is exerted on the ceiling? Neglect the pulley system's mass.  N (upward)

Can someone help with parts a-c?

A diving board of length 3.00 m is supported at a point 1.00 m from the end, and a diver weighing 550 N stands at the free end (Figure 1). The diving board is of uniform cross section and weighs 270 N.

A system comprised blocks, a light frictionless pulley, and connecting ropes is shown in the figure. The B block has a mass of 9.3 kg and is on a perfectly smooth horizontal table. The surfaces of the A block, which has a mass of 8.2 kg, are rough, with Hk = 0.25 between the block and the table. If the C block with mass 9.9 kg accelerates downward when it is released, find its acceleration. A B C.

+ A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. Since the floor is rough, it exerts both a normal force N, and a frictional forcef, on the ladder. However, since the wall is frictionless, it exerts only a normal force N₂ on the ladder. The ladder has a length of L = 4.2 m, a weight of W, = 66.5 N, and rests against the wall a distance d = 3.75 m above the floor. If a person with a mass of m= 90 kg is standing on the ladder, determine the following. (a) the forces exerted on the ladder when the person is halfway up the ladder (Enter the magnitude only.) N₂ N₂- 4- (b) the forces exerted on the ladder when the person is three-fourths of the way up the ladder (Enter the magnitude only.) N₂ N₂ Additional Materials
