NettetQuestion. A drive has a maximum speed of 12,000 revolutions per minute. If a disc has a diameter of 12 cm, what is the linear speed, in km/h, of a point 5 cm from the center if the disc is spinning at a rate of 7000 revolutions per minute? Answer is an integer or a decimal rounded to one decimal place as needed. NettetAngular acceleration α is defined as the rate of change of angular velocity. In equation form, angular acceleration is expressed as follows: α = Δ ω Δ t, 10.4. where Δ ω is the change in angular velocity and Δ t is the change in time. The units of angular acceleration are rad/s /s, or rad/s 2. If ω increases, then α is positive.
