In rolling motion a body possesses translational kinetic energy (K t) as well as rotational kinetic energy (K r) simultaneously. The ratio K t : ( K t + K r ) for the sphere is? Q. Derive an expression for kinetic energy, when a rigid body is rolling on a horizontal surface without slipping.

Therefore, for the disc, the condition for rolling without slipping is given by v cm = R ω. The kinetic energy of such a rolling body is given by the sum of kinetic energies of translational motion and rotation. Where, m is the mass of the body v cm is the translational velocity I is the Moment of Inertia

metrolyrics.com Rolling in the deep is a lyric that originally appeared in the 2010 hit Adele song of the same name. The song itself describes the singer’s vengeful feelings toward an ex-boyfriend. In an interview, she says that the lyrics are telling him to “get the fuck out of [her] house instead of [her] begging him to come back.”

Jul 17, 2016 27 Explanation: The definition of an even number is 2k and for odd 2k +1. We know that a dice has 6 sides and when there are 2 there is a possible of 62 = 36 outcomes. This corresponds to each side from die 1 with each of the 6 sides from die 2. In this case we are interested in only even outcomes.
