A pair of blocks, one more as massive than the other, are connected by a compressed spring. When the spring is released, the blocks fly apart. Compared to the heavier block, the lighter block accelerates at four times the rate of the heavier block. How many times more massive is the heavier block

Asample of a gaseous substance changes into liquid. this process is called (blank) and it takes place when heat is (blank) a gaseous system

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?

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity
