A thread holds two carts together, as shown in Figure 9-9. After the thread is burned, a compressed spring pushes the carts apart, giving the 1.5 kg cart a speed of 23 cm/s to the left. What is the velocity of the 4.5 kg cart? (Answer in cm/s (to the right)) WILL GIVE BRAINLIEST TO THE BEST ANSWER​

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.
