Considering conservation of mechanical energy we have:
K+U (start)= K+U (end)
Where:
K=kinetic energy=
U=potential energy=
So:
0.05*0.95*9.81+0 (start) = 0+K (end)
K (end)=0.5 Joules
K+U (start)= K+U (end)
Where:
K=kinetic energy=
U=potential energy=
So:
0.05*0.95*9.81+0 (start) = 0+K (end)
K (end)=0.5 Joules
