Question

the altitude of an object ,d, can be modeled using the equation below .d=-16t + vt +hfrom the edge of a 486-foot cliff ,peyton shot an arrow over the ocean with an initial upward velocity of 90 feet per second . in how many seconds will the arrow reach the water below ?

Answer 1

Given:

d = -16t + vt + h

Where:

Height, h = 486 ft

Velocity, v = 90 ft per second

Let's find the number of seconds (t) it will take the arrow to reach the water below.

To find the number of seconds, input values into the equation and solve for t.

Thus, we have:

d = -16t + 90t + 48
