Each of the house common rooms at hogwarts has an air hockey table. these tables shoot air up to eliminate friction on the hockey puck. if you tap horizontally on the puck what will happen to it? (see green arrow in picture) a) it will continue to accelerate b) it will slow and stop c) it will move at a constant speed until it hits the side of the table d) it will fly up in the air

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal.find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?
