On the day after graduation, you decide to toss a burning match into the top of a cylindrical wastebasket (diameter D and height 2 D) full of old homework papers. To make this event more sporting, the bottom of the wastebasket is at the same height as the point where the match leaves your hand, and the near side of the wastebasket is a horizontal distance 6 D from the point where the match leaves your hand. You launch the match at a 45.0∘ angle above the horizontal. Find the minimum value of the launch speed that will make the match enter the top of the wastebasket. You can ignore air resistance and give your answers in terms of g and D. Find the maximum value of the launch speed that will make the match enter the top of the wastebasket. Give your answers in terms of g and D.

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s
