Answer:

#312.5J#

Explanation:

  • Firstly I assumed that no energy has been lost in the process. Thus, implying that,

#color(red) (K.E)=color(blue)(G.P.E)#

  • Where:
    1 #color(red)(K.E)# : Kinetic energy
    2#color(blue)(G.P.E)# : Gravitational Potential energy

  • Then

#color(red)(K.E)#=#1/2*m*v^2#
#K.E= 1/2*25*(5)^2#
#K.E=312.5J#

-Then, using the aforementionned assumption, we get,

#color(blue)(G.P.E)=312.5J#

I hope I was useful to help you solve your concern.

Cheers ;).
