A chair is thrown upward from a balcony that's 96 ft in the air, at an initial velocity of 16 ft/s. How many seconds does the chair take to reach its highest height?

t = 6 s

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.

Hence, the chair take 6 seconds to reach its maximum height.
