1) Show that Change in K.E. in Perfectly Inelastic Collision has a negative magnitude.

answered-by-expert Expert Answer
In perfectly inelastic collions, there is permanent deformation in the colliding bodies, which do not recover.
Initial KE = Energy lost in deformation + Final KE.
Change in KE = Final KE - Initial KE = - Energy lost in deformation.
Since the energy lost is always positive, the above statement completely the required proof.

During calculation of acceleration due to gravity above the surface of earth if we assume that there is an external force opposite to that of Earth's gravity then the cos angle will be 180 between the two forces which is negative(-1), if we put the value in the equation of dw = F.dx then the final value of potential energy is positive which is not possible.how and why??
