A squuirrel in a tree drops an acorn How long does it take the acorn to fall 20 feet?

The time it takes for an acorn to fall 20 feet can be estimated using the formula for free fall: ( t = \sqrt{\frac{2d}{g}} ), where ( d ) is the distance (20 feet) and ( g ) is the acceleration due to gravity (approximately 32 feet per second squared). Plugging in the values, ( t \approx \sqrt{\frac{2 \times 20}{32}} ), which results in about 1.12 seconds. Therefore, it takes roughly 1.12 seconds for the acorn to fall 20 feet.
