answered-by-expert Expert Answer

Pf = 1.5Pi

Ekf = Pf2/2m

= 1.5Pi2/2m

= 2.25Pi2/2m

= 2.25Eki

Percentage increase in kinetic energy = (Ekf - Eki)x100/Eki = 125%

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??
