1. The problem statement, all variables and given/known data 38. (b) Is it possible to be accelerating if you are traveling at constant speed? Explain your answer. (d) Explain why, in American football, a field goal is kicked from the ground while a punt is drop kicked. (f) Reaching out from a balcony, you throw rock A vertically upward. Then you throw rock B vertically downward from the same release point and with the same initial speed as rock A. If you neglect air resistance, which rock has the higher speed just before it hits the ground? 2. Relevant equations None, I believe. 3. The attempt at a solution (b) No, traveling at constant speed is a straight diagonal line on a position graph. That means that there's no change in spped. No change in spped means no change in velocity (which is the slope of speed). With velocity then having a 0 slope, there is no acceleration (slope of velocity). -1 (d) This is done to change the angle of where the football is projected to go. Until 90 degrees, items are projected to go farther if the angle is higher. -2 (f) Throwing a rock downward vertically will cause its speed to be higher than if it was thrown upward. -1 I had points taken off for my answers, and I'm not sure why. Could someone explain to me what's wrong with my answers? Thank you.
