Answer:
Option D
Step-by-step explanation:
By using geometric mean theorem in the given right triangle ABC,
BD² = AD × DC
h² = (AC - CD) × DC
h² = (25 - 16) × 16
h² = 9 × 16
h =
h = 12
Therefore, measure of side h = 12 units.
Option D will be the correct option.
Answer:
144 ft
Step-by-step explanation:
The speed decreases linearly by 32 ft/sec/sec, so will be zero after ...
(96 ft/s)/(32 ft/s²) = 3 s
The average speed over that period is half the initial speed, so the distance covered between the ground and the maximum height is ...
(3 s)(96 ft/s)/2 = 144 ft
_____
<em>Alternate solution</em>
The relationship between velocity and distance for a constant acceleration is ...
For an initial velocity of 96 ft/s, a final velocity (at the top of travel) of 0, and the given acceleration, we have ...
