Answer:
5 seconds
1220 ft
Step-by-step explanation:
Step 1: Know when the stone reaches the maximum height
We know the maximum or minimum height of a parabola is at the vertex so we need to find the vertex
Step 2: Calculate the vertex
The t coordinate of the vertex can be calculated with
b = 160
a = 16
Step 3: We know the t coordinate we can find the height at that time
Therefore the stone reaches its maximum height of 1220 ft in 5 secs
