A basketball player shoots a free-throw with initial velocity vo: 7.5 m/s at an angle -28" above the horizontal. Use a Cartesian coordinate system with the origin located at the position the ball was released, with the ball's horizontal velocity in the positive x direction and vertical component in the positive y resistance. -direction. Assume the basketball encounters no air a 50% (a) Determine the maximum vertical height hma , in meters, the ball attains above the release point.
(b) Determine the maximum vertical height h a , in meters, the ball attains above the release point. Determine the time,1 in seconds, the basketball takes to reach its maximum vertical height.

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
