"You are standing on a ladder, helping with some repairs at home. You drop a hammer and it hits the floor at a speed of 4 feet per second. If the acceleration due to gravity (g) is 32 feet/second^2 , how far above the ground (h) was the hammer when you dropped it? Use the formula
V= square root 2gh
A. 16.0 feet
B. 1.0 foot
C. 0.25 feet
D. 0.5 feet"

Step 1I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2: Identify the Given Information
- Acceleration due to gravity (g) = $$32 \frac{\mathrm{feet}}{\mathrm{second}^{2}}
- Final velocity (V) = 4 feet/second - We need to find the initial height (h)
Final Answer
Key Insights: - The equation V = \sqrt{2gh} relates velocity, gravity, and height - Rearranging allows us to solve for height when velocity is known - Always check units to ensure correct calculation
