25 points! 1.) Equally massive cars collide, where one was stationary and the other was moving to the right. What is the end result of this collision and explain how you know this
2.) If a clay ball of a mass 1.5 kg moving at speed 6 m/s to the right, collides and sticks to a stationary ball of mass 4 kg what is the end movement of the new mass.

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.

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot

How are positive ions different from neutral atoms
