7 A stationary gun of mass 4.8kg mounted on wheels is in a battlefield At fires a bullet of mass 85g to the right with a velocity of vms The bullet moves horizontally and hits a stationary
wooden block of mass 5.6kg. It gets imbedded in the block. The bullet-block system then moves
a distance 10.78m and comes to rest in a time of 4.5 seconds.

if they have a finite resultant

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
