Answer: 18 blocks in total ( 17 add to the original in contact with the ground)
Explanation:
The pressure on the face in contact with the ground ( we choose the face 0.15m x 0.082m)
Pressure= Force ( weigth) /Area
1 Atm = 101325 Pascal [N/ m^2]
Answer:
D is the correct answer
Explanation:
A) shows low accuracy and high precision since they missed the bull's-eye but are all grouped together.
B) Shows high accuracy and high precision
C) Shows high precision
D is the only one that shows both low accuracy and low precision

<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
Some call it "air resistance", and others just call it "drag".
Ok? I don’t know what you want me to do though
