Question #eeed8

Answer 1

`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 ;).
