A 5.9 kg bowling ball is traveling toward a wall at 34 m/s. The bowling ball bounces off the wall at a velocity of 18 m/s. If the ball is in contact with the wall for 0.65 seconds, what magnitude force was applied to the ball by the wall? Round to whole number. Help please.

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.
