An object falls from rest on a high tower and takes 5.0 s to hit the ground. calculate the object's position from
the top of the tower at 1.0 s intervals. make a position-time graph for the object's motion. in your response,
show what you are given, the equation that you used, any algebra required, a table of data, and your graph.
g = 9.8 m/s2

Amachinist needs to remove a tight fitting pin of material a from a hole in a block made of material b. the machinist heats both the pin and the block to the same high temperature and removes the pin easily. what statement relates the coefficient of thermal expansion of material a to that of material b? a) the situation is not possible, heating block b will shrink the hole in the material as the material expands with increasing temperatureb) material b has the same coefficient of expansion as does material ac) material b has a negative coefficient of expansion and a has a positive coefficient of expansiond) material a has a greater coefficient of expansion than does material be) material b has a greate
