What is thecoefficient of static friction such that the block stays at rest?(49) During another experiment, a student places the same large block on a plank.The student raises one end of the plank until the block starts to slide down.Another classmate explains that the block begins to slide because the parallelcomponent of the surface force exerted on the block by the plank increasesas the plank is lifted higher.

As a horse and wagon are accelerating From rest, the horse exerts a force of 400 N on the wagon (Figure 2.56), Illustrating Newton's third law, the wagon exerts an equal and opposite force of 400 N.
