use a(t)=-32 feet per second squared as the acceleration due to gravity. A ball is thrown vertically upward from the ground with
liberstina [14]

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 ...

  v_f^{2}- v_i^{2} = 2ad

For an initial velocity of 96 ft/s, a final velocity (at the top of travel) of 0, and the given acceleration, we have ...

  d = \dfrac{v_f^{2}- v_i^{2}}{2a} = \dfrac{0-96^{2}}{2(-32)}= 144\,\dots\ \text{ft}

<h3><u>Answer: 321</u></h3><h2>Your explanation</h2>

There where 28 classrooms that donated. If we are to estimate the total, then we must round the canned items. They're 8982 canned items. If you round that number, you get 9000. So you want to divide 9000 and 28.

____ [38]

9514 1404 393

Answer:

  • up the wall: 4√3 ft ≈ 6.9 ft
  • along the ground: 4 ft

Step-by-step explanation:

The side ratios in a 30°-60°-90° triangle are 1 : √3 : 2. Since the hypotenuse of this triangle is 8 feet, the multiplier of these ratio values is (8 ft)/2 = 4 ft.

The triangle sides are ...

  4 ft : 4√3 ft : 8 ft

The ladder reaches 4√3 ≈ 6.9 ft up the wall. Its base is 4 ft from the building.
