-) A basketball player is running at +8.0 m/s when a bus passes her. The bus accelerates from +20.0 m/s to +25.0 m/s in 10,0 s. The jogger speeds up with the same acceleration
of the bus over 20,0 s. What is the jogger's new velocity? (HINT: What would the formula
for final velocity look like?) Show all of your work for full credit.

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
