Edmunds.com bases the luxury type on the model's nameplate: Audi, BMW, Cadillac, Lexus, Mercedes-Benz and the like. However, some listed vehicles bear the nameplates of brands that are not typically considered luxury marques. These vehicles typically achieve luxury status because of their price.
A bowling ball encounters a 0.760 m vertical rise on the way back to the ball rack. Ignore frictional losses and assume that the mass of the ball is distributed uniformly. The translational speed of the ball is 4.70 m/s at the bottom of the rise. Find the translational speed at the top. Add your answer.
E(k-total)=E(k-linear) + E(k-rotational) E(k-total)=(mv^2)/2 +(Iw^2)/2 I=(mh^2)/12 +(mr^2)4 m-mass of the cylinder r-radius h-height v=2Pi r/t linear speed w=v/r rotational speed We have E(k-total) = = (mv^2)/2 + ((mh^2)/12 +(mr^2)4)(v/r)^2 = = mv^2 (1+ (h^2)/12 + 1/4)= =mv^2(15+ h^2)/12).hat means the speed of the surface of the cylinder equals the translational velocity of the cylinder; it's just going the opposite direction. In other words, the translational velocity of the cylinder is all you need. The total kinetic energy equals the translational and the rotational kinetic energy.
