Answer:

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
