Answer:

209.236

Explanation:

Order of Operations: PEMDAS

"Please excuse my dear Aunt Sally"

Parentheses, exponents, multiplication, division, addition and subtraction

First use p=mv

Player:(plug in the data)

= 87.2*2.87

= 250.264

Bullet : (do the same)

Then subtract Bullet-Player =209.236

<h3>Answer:</h3>

209.236 kg · m/s

<h3>General Formulas and Concepts:</h3>

<u>Math</u>

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition

  • Left to Right

<u>Physics</u>

<u>Momentum</u>

Momentum Formula: P = mv

  • P is momentum (in kg · m/s)
  • m is mass (in kg)
  • v is velocity (in m/s)
<h3>Explanation:</h3>

<u>Step 1: Define</u>

m₁ = 87.2 kg

v₁ = 2.87 m/s

m₂ = 0.0520 kg

v₂ = 789 m/s

<u>Step 2: Find Momentums</u>

<em>Football Player</em>

  1. Substitute [MF]:                    P = (87.2 kg)(2.87 m/s)
  2. Multiply:                                P = 250.264 kg · m/s

<em>Bullet</em>

  1. Substitute [MF]:                    P = (0.0520 kg)(789 m/s)
  2. Multiply:                                P = 41.028 kg · m/s

<u>Step 3: Find difference</u>

  1. Define equation:                    P₁ - P₂
  2. Substitute:                              250.264 kg · m/s - 41.028 kg · m/s
  3. Subtract:                                 209.236 kg · m/s

large cylindrical water tank is mounted on a platform with its central axis vertical. The water level is 3.75 m above the base o
eduard

Answer:

0.0000333 m³/s

Explanation:

using Bernoulli's equation

P1 + 1/2ρv1² + ρh1g = P2 + 1/2ρv2² + ρh2g

P1 = P2 both are atmospheric pressure; they cancel out

1/2ρv1² + ρh1g = 1/2ρv2² + ρh2g divide both side with ρ (rho)

1/2v1² + h1g = 1/2v2² +h2g

collect the like terms

h1g - h2g = 1/2v2² + 1/2v1²

multiply both side by 2 and take g out from the left equation

2g(h1 - h2) = v2² + v1² where v1 is approximately 0 assuming the surface of the tank is large

v2² = 2g(h1 - h2)

take square root of both sides

v2 = √2g(h1 - h2)

h1 = 3.75 + 6.5 = 10.25

h2 = 6.5

v2 = √2g(h1 - h2) = √ (2×9.81× (10.25 - 6.5)) = 8.6 m/s

Volume in m³/s = A × v where A is the area of the hole  and the radius of the hole = 2.22 mm / 2 (where 2.22 mm is the diameter of the hole) = 1.11 mm and  1.11mm / 1000 to convert it to meters

Area of the hole ( assuming it is a circle) = πr² = 3.142× (1.11/1000)²

Area = 0.00000387 m²

Volume in M³/s = 0.00000387 × 8.6 = 0.0000333 m³/s
