A blue ball is thrown upward with an initial speed of 21.4 m/s, from a height of 0.9 meters above the ground. 2.6 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 9.4 m/s from a height of 25.3 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2.

A motorcycle and a minivan are at rest, side by side, at a stoplight. A pickup truck is approaching the intersection from behind the motorcycle and minivan, at 20 m/s. At the instant the traffic light turns green, t=0s, the pickup truck is 140m behind the minivan. When the light turns green, the motorcycle accelerates at 4 m/s^2 for 5 seconds, while the minivan accelerates at 2m/s^2 for ten seconds. Once each vehicle stops accelerating, it maintains a constant speed.

10 points possible Due Mar 6 11.59pm H01 Unit H Discussion Romeo cannot stand the sight of red-headed women. He gets very angry, not fearful, when he sees any woman with red hair. He wants to hit thep or throw something at them, though he may not even know them. Red-headed men don't upset him, and he has no problems eating strawberries or other red foods, so he doesn't understand his anger himself. Romeo is up for a promotion at work, and he really wants the job, but he would be working with - guess what? Not one, but TWO red-headed women! This has finally prompted him to see a psychologist who specializes in psychoanalysis. How might this psychoanalyst treat Romeo? Can you offer any clues as to what may be the root of his problem?
