Q. A pitcher's arm rotates at a speed of 7 degrees per millisecond (ms degrees ).At what speed does the pitcher's arm rotate in s degrees ?s degrees
Given speed conversion: We are given the speed of the pitcher's arm rotation in degrees per millisecond, which is 7 degrees per millisecond. To convert this speed to degrees per second, we need to know how many milliseconds are in one second.
Milliseconds in one second: There are 1000 milliseconds in one second. Therefore, to convert the speed from degrees per millisecond to degrees per second, we multiply the given speed by 1000.
Calculate speed in degrees: Calculating the speed in degrees per second: 7degrees/ms×1000ms/s=7000degrees/s.
Final speed calculation: The pitcher's arm rotates at a speed of 7000 degrees per second.
