Awoman bails out of an airplane at an altitude of 10,000 ft, falls freely for 20 s, then opens her parachute. how long will it take her to reach the ground? assume linear air resistance pv ft/s^2, taking p =.15 without the parachute and p=1.5 with the parachute. i really mostly need to know how to set this up? what are some hints? i know terminal velocity and gravitational acceleration are involved but i don't get how to do it.

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
