The graph represents the distance a major league outfielder throws a baseball. He can throw as fast as 105 miles per hour or 154 feet per second which equation represents this scenario

1 answer

To convert the speed of the outfielder's throw into feet per second, we can use the fact that 1 mile is equal to 5280 feet and 1 hour is equal to 3600 seconds.

Step 1: Convert miles per hour to feet per second.

  1. Given speed: 105 miles per hour

  2. Convert miles to feet: \[ 105 \text{ miles} = 105 \times 5280 \text{ feet} \]

  3. We convert hours to seconds: \[ 1 \text{ hour} = 3600 \text{ seconds} \]

Now, calculate the speed in feet per second: \[ \frac{105 \times 5280 \text{ feet}}{3600 \text{ seconds}} \]

Calculating this: \[ 105 \times 5280 = 554400 \text{ feet per hour} \] \[ \frac{554400}{3600} \approx 154 \text{ feet per second} \]

The conversion confirms that 105 miles per hour is indeed approximately 154 feet per second.

Step 2: Find relevant equations to represent his throwing scenario.

Since the throw's speed has been established as 154 feet per second, the distance \( d \) that the ball travels can be modeled as a function of time \( t \). The basic equation you'd use in this scenario (assuming constant velocity without considering air resistance) is:

\[ d = r \cdot t \]

Where:

  • \( d \) is the distance thrown (in feet),
  • \( r \) is the rate of throwing (which we've found to be 154 feet per second),
  • \( t \) is the time (in seconds).

Substituting the known value into the equation, we get:

\[ d = 154 \cdot t \]

Thus, the equation that represents the outfielder's throw in feet as a function of time in seconds is:

\[ d = 154t \]

This equation models the distance thrown based on the throw speed of the outfielder.
