Answer:

hope it helps

Explanation:

m=3kg                                            velocity ateer 3

h=25m                                            second will be

                                                   v= u + gt

                                                   =0+10X3=30m/s

       K.E= ½ X m X v ²

    = ½  X 3  X (30)²  = ½ X 3 X  900

                                                = 1350 jule.  ans
