Answer:
31.005 KJ
Explanation:
We are given that
Mass of hammerhead=25 kg
Initial velocity,u=0
Final velocity,v=50 m/s
h=-1 m
h'=0
We have to find the change in total energy of the hammerhead.
Change in total energy=
Using the formula
Change in internal energy of hammerhead=
Change in total energy=
Where
Change in total energy=
1 KJ=1000 J
