17. a 1350 g projectile is launched with a force of 150 n. the length of the firing arm is 1.25 m.
a. determine the exit velocity of the projectile.
b. determine the maximum height the projectile achieved
c. what is the total time the projectile travelled?
d. determine the distance the projectile travelled if the launch angle is 42 degrees from the horizontal
and the target is 27 meters below the launcher.

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
