The total I is four times this moment of inertia because there are four blades. Thus, I = 4 M l 2 3 = 4 × ( 50.0 kg) ( 4.00 m) 2 3 = 1067.0 kg · m 2. WebAug 20, 2015 · So to get an average velocity between two events first compute the vector A between the two events. Then project that A onto your unit tangent W to get the projection P. Then the vector A equals P+R with the rejection R orthogonal to the projection P. We get R from R=A-P. And if we divide R by the length of P we get the velocity of A relative to W.
