Problem 03.099 – Position vector Skip to question A particle has a constant acceleration of 5.00 m/s2 to the east. At time t = 0, it is 2.00 m east of the origin and its velocity is 20.0 m/s north. Take +x as east and +y as north. Problem 03.099 – 1 – x-component of position vector What is the x-component of its position vector at t = 2.80 s? Enter a positive answer if the x-component is due east and a negative answer if the x-component is due west.

A major leaguer hits a baseball so that it leaves the bat at a speed of 30.7 m/s and at an angle of 35.8 above the horizontal. You can ignore air resistance. Calculate the horizontal component of the baseball's velocity at a later time calculated in part (a). $v_x$ = Calculate the vertical component of the baseball's velocity at a later time calculated in part (a). $v_y$ = What is the magnitude of the baseball's velocity when it returns to the level at which it left the bat?

S2. (modified) Consider a population in which there are two phenotypes: natural-born cooperators (who do not confess under questioning) and natural-born defectors (who confess readily). If two members of this population are drawn at random to play a prisoners' dilemma game, their payoffs in a single play are shown below: Column Confess (defect) Not (cooperate) Row Confess (defect) -10, -10 -1, -25 Not (cooperate) -25, -1 -3, -3 a. Suppose that a pair of players plays this dilemma twice in succession. Draw the payoff table for the twice-repeated dilemma with A (always defect) and T (play tit-for-tat, staring with not defecting) as the two available strategies. Column A (always defect) T (Tit-for-Tat) Row A (always defect) T (Tit-for-Tat)

Three masses lie on the x-axis. Object A is at the origin and has a mass of 829.1 kg. Object B has a mass of 321 kg and is located 5.6 meters in the positive x direction from A. Finally, object C, which has a mass of 618.4 kg, is positioned 4.7 meters from object B, so that object B is between objects A and C. What is the force acting on object B?
