If you square the hypotenuse, you get 20^2, which equals 400 N. 10^2 + (10sqrt (3))^2 = 100 + 300, which equals 400 N, or the hypotenuse squared. Therefore, those are the two components of the force, proven by the Pythagorean theorem.

WebAngular 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.
