Two football players kicked the ball from opposite ends of the field which is 100 m long. Player A kicked the ball with the initial velocity vA0 so that the ball reaches maximum distance. Player B however
kicked with twice the initial velocity of that of player A. Both players kicked the ball simultaneously and both
balls hit the ground at the same time. What is the initial velocity (both magnitude and direction), total time of
flight, and the maximum height that the ball reached in each case?

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
