Answer:

h=25

Step-by-step explanation:

From the question we are told that:

Velocity v=40fts

The height h function

 \large h=-16t^2+40t

Generally time t is mathematically given by

 h'=-32t+40

 -32t+40=0

 t=\frac{40}{32}

 t=1.25

Therefore  the ball's maximum height is given as

  \large h=-16(1.25)^2+40(1.25)

 \large h=-16(1.25)^2+40(1.25)

 h=25

xeze [42]

The motion of the rock thrown from the cliff which goes downwards due to

the gravitational force, is a free fall motion.

  • 125 represents; <u>A. The initial height of the rock</u>.

Reasons:

The given function that represents the height of the of the rock in feet <em>x</em> seconds after being thrown is; f(x) = 16·x² + 4·x + 125

At the initial height before being thrown from the cliff, we have;

The time, x = 0

The initial height is therefore;

The initial height f(0) = 16 × (0)² + 4 × (0) + 125 = 125

125 represents <u>A. The initial height of the rock</u>
