Because of the conditions that give rise to them, tornadoes do not have
the widespread destructive effects of hurricanes. Nevertheless, the
winds encountered in some tornadoes are even greater than those at
the eyewall of a hurricane. Suppose a small pebble is swept up in a tor-
nado. The pebble is 3.81 m from the center of the tornado and has a
tangential speed equal to that of the surrounding wind: 124 m/s. What
is the magnitude of the centripetal acceleration of the pebble?

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?
