A disc is rolling (without slipping) on a horizontal surface. C is its center and Q and P are two points equidistant from C. Let VP,VQ and VC be the magnitude of velocities of points P,Q and C respectively, then A disc is rolling (without slipping) on a horizontal surface. C is its center and [...]

A particle of mass m moves in the XY plane with a velocity v along the straight line AB. If the angular momentum of the particle with respect to origin O is LA when it is at A and LB when it is at B, then A particle of mass m moves in the XY [...]
