Answer:
Step-by-step explanation:
so the question is asking about the time from 1500 feet to 1100 feet. How long did they fall, w/o a parachute. aka "freefall" so, at 1500 feet the jumper is really at time zero. so, plug in to the formula
1100 = -16
+1500
( x represents seconds so i'll change it to t so we know it's time )
1100 = -16
+ 1500
now we can solve for t , to see how long the jumper falls
-400 = - 16
( subtracting 1500 from both sides of equation )
25 =
( dividing both sides by -16 )
oh.. look at how nice that turns out.. :)
= t ( take the square root on both sides )
5 = t
the jumper fell for 5 seconds to get to 1100 feet
