A girl in a bumper car (with a combined mass of 230 kg) is traveling at 3.8 m/s due north. A boy in a bumper car (with a mass of 220 kg) also is traveling due north ahead of the girl but is moving at only 1.5 m/s. The girl catches the boy’s bumper car and they have a collision. Afterward, the boy is traveling at 3.1 m/s north. What is the magnitude and velocity of the girl’s bumper car? (Round your answer to the nearest tenth.)

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.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
