wait... where did u get the 100?

what do i do form here?:confused:

i'm still a little confused. so what would be the constant?

I understand

0?:confused:

is the initial velocity=0ms-1

the potential energy=mass*gravity*height =10*10*m =100m

how do i find it?I was not given to velocity or mass

isn't it 0J
