You will need data that logs the changes in speed from various, consecutive events. Which you can use to calculate the difference in speed and determine wether the speed is increasing or increasing.

Otherwise, you only need the initial and finak value to find the difference.

$final \: - \: initial \: = \: difference$

Answer:

x = 1.5

Step-by-step explanation:

Here, we want to solve for the value of x

By using the tangent from the same point theorem, we have it that;

lh^2 = lj * lk

1^2 = (0.5) * (0.5 + x)

1 = 0.5x + 0.25

1-0.25 = 0.5x

0.5x = 0.75

x = 0.75/0.5

x = 1.5

An object is thrown upward from the top of an 80ft tower. The height h of the object after t seconds is represented by the quadr

dybincka [34]

0 = -16t²+64t+80

Finding the roots of the equation:

-16(t² - 4t - 5) = 0

-16(t-5)(t+1) = 0

t = 5, t = -1. Time cannot be negative, so after 5 seconds it will hit the ground.
