Determine the rotational speed of the drill of an electric drill if the angular velocity is 400pi.
| May 20, 2021 | education
w = 400 * п.
п = 3.14.
v -?
The angular speed w and the frequency v of rotation are related to each other by the formula: w = 2 * п * v, where п is the number pi.
The formula for determining the frequency v of rotation will be: v = w / 2 * п.
v = 400 * п / 2 * п = 200 Hz.
Answer: The rotational speed of the drill is v = 200 Hz.
