"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

<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>
Substitute [MF]: P = (87.2 kg)(2.87 m/s) Multiply: P = 250.264 kg · m/s <em>Bullet</em>
Substitute [MF]: P = (0.0520 kg)(789 m/s) Multiply: P = 41.028 kg · m/s
<u>Step 3: Find difference</u>
Define equation: P₁ - P₂ Substitute: 250.264 kg · m/s - 41.028 kg · m/s Subtract: 209.236 kg · m/s
