10.4 Moment of Inertia and Rotational Kinetic Energy

Web7 apr. 2024 · A two-kilogram mass (something weighing 4.4 pounds on Earth) moving at a speed of one metre per second (slightly more than two miles per hour) has a kinetic energy of one joule. In the centimetre-gram-second system the unit of energy is the erg, 10 −7 joule, equivalent to the kinetic energy of a mosquito in flight. Web6 sep. 2016 · All moving objects have momentum $p=mv$, and conservation of momentum says: $$\sum p_ {before} =\sum p_ {after} $$ So in you case: $$ p_ {before} = p_ {after} \quad\Leftrightarrow\quad m_1v_1=m_2v_2$$ The old and new mass as well as old speed are known, so new speed can be calculated.
