Question #6a) you were told to assume that the ball bounced to a height of 1.2 m and that the distance between the bounces measured along the floor was 0.5 m. assume that the height of the bounce were less than before, but the distance between bounces were still the same, and complete the following predictions. the horizontal velocity would be (greater/same/less) before. the time between bounces would be (greater/same/less) before. the magnitude of the acceleration of the ball would be (greater/same/less) before. the maximum vertical velocity (right after the first bounce) would be (greater/same/less) before. b) which of the following statements are evidence that the motion in the x and y coordinates can be treated separately? select each accordingly. evidence/not evidence : from the graphs of x(t) and y(t), we can see that acceleration happens only in the y coordinate. evidence/not evidence : the time of flight of a bounced ball depends only on the initial y velocity after the first bounce. evidence/not evidence : the acceleration of free-fall is constant. evidence/not evidence : it takes the same amount of time for a dropped ball to reach the floor as it does for a ball that is launched horizontally from the same height. evidence/not evidence : the component equations of x(t) and vx(t) contain no functions of y or vy, and the component equations of y(t) and vy(t) contain no functions of x or vx. evidence/not evidence : a line fit to vy(t) can be used to find the acceleration in the y direction.

The second largest public utility in the nation is the sole provider of electricity in 32 counties of southern florida. to meet the monthly demand for electricity in these counties, which is given by the inverse demand function p = 1,200 – 4q, the utility company has set up two electric generating facilities: q1 kilowatts are produced at facility 1, and q2 kilowatts are produced at facility 2 (so q = q1 + q2). the costs of producing electricity at each facility are given by c1(q1) = 8,000 + 6q12 and c2(q2) = 6,000 + 3q22, respectively. determine the profit-maximizing amounts of electricity to produce at the two facilities, the optimal price, and the utility company’s profit
