Q. A pitcher's arm rotates at a speed of 7degreesms7 \frac{\text{degrees}}{\text{ms}}. At what speed does the pitcher's arm rotate in degreess\frac{\text{degrees}}{\text{s}}? \newlinedegreess\frac{\text{degrees}}{\text{s}}
  1. Convert to Seconds: First, we need to convert milliseconds to seconds. 11 second == 10001000 milliseconds.
  2. Pitcher's Arm Rotation: The pitcher's arm rotates at 77 degrees per millisecond. So, in 11 second, it rotates 77 degrees imes1000 imes 1000 milliseconds.
  3. Calculate Rotation Speed: Calculate the rotation speed in degrees per second. 71000=70007 * 1000 = 7000 degrees per second.
