Answer:
8
Step-by-step explanation:
Hope it helps you in your learning process.
The height of the building comes to be 81 feet.
Initial velocity u= 0 feet/sec
Final velocity v= 72 feet/sec
The acceleration due to gravity g =32ft /sec²
Height of the building h= suppose h
<h3>What is the equation of motion?</h3>
The equation of a motion is:

Where u and v are the initial and final velocities.

So, the height of the building = 81 feet.
Therefore, the height of the building comes to be 81 feet.

Answer:
2
Step-by-step explanation:
Given expression:
y^2 - 5y - 4
y = 6
Substitute y = 6 into the expression
y^2 - 5y - 4
6^2 - 5(6) - 4
(6*6) - (5*6) - 4
36 - 30 - 4
36 - 34
2
The value of the expression y^2 - 5y - 4 is 2 when y = 6
Answer:
The answer is -2
