Answer:
t = 1.1 sec for first time and then in
t = 3.9 sec
Explanation:
The function for the height of the circus performers is:
where t is seconds after launch
h is height in feet
For calculating after how many seconds is the performer at 100 feet above the ground, we must equal the equation to 100 and to find t:
Then,
t = 3.9 sec
t = 1.1 sec
