Math Problem Statement

A basketball player's hang time is the time spent in the air when shooting a basket. The formula t = √d/2 models hang time, t, in seconds, in terms of the vertical distance of a player's jump, d, in feet. When a particular player dunked a basketball, his hang time for the shot was approximately 1.23 seconds. What was the vertical distance, d, of his jump, rounded to the nearest tenth?

Solution

We are given the formula for the hang time tt, which is expressed as:

t=d2t = \frac{\sqrt{d}}{2}

where dd is the vertical distance (in feet) and tt is the hang time (in seconds). We are asked to find the vertical distance dd when the player's hang time is t=1.23t = 1.23 seconds.

Steps to solve for dd:

  1. Start with the equation: t=d2t = \frac{\sqrt{d}}{2} Substitute t=1.23t = 1.23: 1.23=d21.23 = \frac{\sqrt{d}}{2}

  2. Multiply both sides by 2 to isolate d\sqrt{d}: 2×1.23=d2 \times 1.23 = \sqrt{d} d=2.46\sqrt{d} = 2.46

  3. Square both sides to solve for dd: d=(2.46)2d = (2.46)^2 d=6.0516d = 6.0516

  4. Round dd to the nearest tenth: d6.1feetd \approx 6.1 \, \text{feet}

Final Answer:

The vertical distance dd of the player's jump is approximately 6.1 feet.
