Answer:

Total change in energy = 31 KJ.

Explanation:

Mass m=25 kg

Height h = 1 m

Initial velocity = 0

Final velocity = 50 m/s

Energy at initial condition

$E_1=mgh+\dfrac{1}{2}mv^2$

$E_1=25\times 10\times 1+0$

$E_1=250\ J$

Energy at final condition

$E_2=0+\dfrac{1}{2}\times 25\times 50^2$

$E_2=31250\ J$

So the change in energy = 31250 -250 J

The total change in energy = 31000 J
