HW P. 150 #’s 2, 3 Lucy and her friend are working at an assembly plant making wooden toy giraffes. At the end of the line, the giraffes go horizontally off the edge of the conveyor belt and fall into a box below. If the box is 0.6m below the level of the conveyor belt and 0.4 meters away from it, what must the horizontal velocity of the giraffes be as they leave the belt if they are to land in the box? You are visiting a friend from elementary school who now lives in a small town. One local amusement is the ice-cream parlor where Stan slides his completed ice-cream sundaes down the counter at a constant speed of 2.0 m/s to the servers. IF the servers catch the sundaes .07 horizontal meters away from the counter, how far have the sundaes fallen before they are caught?
