Answer:
t = 6 s
Step-by-step explanation:
Given that,
A chair is thrown upward from a balcony that's 96 ft in the air, d = 96 ft
The initial velocity of chair, u = 16 ft/s
We need to find how many seconds does the chair take to reach its highest height. Let the time is t.
![t=(d)/(v)\\\\t=(96\ ft)/(16\ ft/s)\\\\=6\ s](https://img.qammunity.org/2021/formulas/physics/college/25sn46qgrs4o3s5hhvl46gt6t9zh46ckc0.png)
Hence, the chair take 6 seconds to reach its maximum height.
