A stone is thrown straight up from the edge of a roof, 725 feet above the ground, at a speed of 16 feet per second. C. What is the velocity of the stone when it hits the ground?

216 ft/s.

Step-by-step explanation:

Displacement (s) =  -725 ft

Initial speed (u) = 16 ft/s

Acceleration due to gravity (g) = -32 ft/s/s.

We can use the equation of motion v^2 = u^2 + 2gs

v^2 = 16^2 + 2 * -32 * -725

v^2 = 256 + 46400

v^2 = 46,656

V = 216 ft/2.

c is the final answer! : )

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
