Acar slows down at -5.00 m/s^2 until it comes to a stop after traveling 15.0 m. what was the initial speed of the car?

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.

What are similarities and differences between refraction, reflection, diffraction and absorption?
