Discussion One: (8.28 – 9.3) Question 1: My friend on the moon would have won the prize with the greatest value (A). This is because newton (N) is the measurement of weight, not mass. My friend and I both won the same weight in gold but the mass of his/hers must be larger in order to compensate for the moon’s lower gravity. He/she won a greater mass in gold thus has the greater value. Question 2: Although I tossed a ball upward at 40 m/s with no air resistance, I must account for the gravitational pull which is 9.8 m/s^2 and what speed we are calculating to. So I come up with 40 m/s – 7s(9.8 m/s^2) – initial velocity minus time(gravity) – and I find the answer -28.6 m/s. A speed cannot be negative so we get 28.6 m/s after 7 seconds. Response: D'Andre, I appreciate how you went above and beyond finding out exactly how much different the gravitational pull is on the moon versus earth. Really shows how much more your (our?) friend won.I am glad we are all on the same page about speed not being a negative. You
