QuestionA pitcher's arm rotates at 7 degrees/ms. What is the speed in degrees/s?

Studdy Solution

STEP 1

Assumptions1. The pitcher's arm rotates at a speed of7 degrees per millisecond. . We want to convert this speed to degrees per second.

STEP 2

First, we need to understand the relationship between milliseconds and seconds. There are1000 milliseconds in1 second.

STEP 3

To convert the speed from degrees per millisecond to degrees per second, we need to multiply the given speed by the number of milliseconds in a second.
$Speed_{\frac{degrees}{s}} = Speed_{\frac{degrees}{ms}} \times Number\, of\, milliseconds\, in\, a\, second$

STEP 4

Now, plug in the given values for the speed and the number of milliseconds in a second to calculate the speed in degrees per second.
$Speed_{\frac{degrees}{s}} =7\, \frac{degrees}{ms} \times1000\, ms$

STEP 5

Calculate the speed in degrees per second.
$Speed_{\frac{degrees}{s}} =7\, \frac{degrees}{ms} \times1000\, ms =7000\, \frac{degrees}{s}$ The pitcher's arm rotates at a speed of7000 degrees per second.
