False.
It is important to know what is around you when making decisions
Possibly the third one down. I don't think that DNA was around in Crippen's time. I'm not a criminologist or associated fun and games, though.
Answer: 258.7 J
Explanation:
Velocity of object V=5m/s
Mass ; 5kg
Height; h=4m
Mechanical energy is equal to sum of kinetic and potential energy
E=K+Ep
Kinetic energy is calculeted using; K=m*V²/2
Potential energy is calculated using : Ep=m*G*h
-------------------------------------------------------------------------
V=5m/s
m=5kg
h=4m
E=K+Ep
E=m*V²/2+m*G*h
E=5kg*(5m/s)²/2+5kg*9.81m/s²*4m
E=62.5J+196.2J
E=258.7 J
