... In classical mechanics, mechanical energy (kinetic + potential) of an object is closely related to its momentum and mass Since in SR we have redefined the classical mass and momentum to that of relativistic version mclass(cosnt) –> mSR = m0g pclass = mclass u –> pSR = (m0g)u we must also modify the ...

... the rod is anchored to a frictionless pivot. Initially the masses are horizontal, but after releasing them, they swing in a vertical plane. a) How far from the pivot is the center-of-mass? c.m. = (1 x 3 + 2 x 6)/(1 + 2) m = 5.0 m b) If all of the mass is placed at the center-of-mass, then how much w ...

If the component of the net external force on a closed system is zero along an axis, then the component of the linear momentum along that axis cannot chang ...

... 8. A horizontal platform in the shape of a circular disk rotates freely in a horizontal plane about a frictionless, vertical axle. The platform has a mass M = 100 kg and a radius R = 2.00 m. A student whose mass is m = 60 kg walks slowly from the rim of the disk toward its center. If the angular spe ...
