Question

The tachometer in the author's car has a maximum reading of 16,000 rpm. (A tachometer is a gauge that shows the angular speed of a car's engine.) Express this angular speed in rad/s.

Answer 1

Answer:

the angular speed in rad /s is  1675.516 rad/s

Explanation:

The computation is shown below;

The Tachometer's reading is

= 16000 rpm

= 266.67 rps

Now

angular speed ,w = 2 × $\pi$ ×freq

= 2 × 3.14 × 266.67

= 1675.516 rad/s

Hence, the angular speed in rad /s is  1675.516 rad/s

The same is to be considered by applying the above formula so that the correct speed could arrive
