1. The problem statement, all variables and given/known data
How would doing this experiment in the moom effect the experiment ?

"the experiment in lunching a ball against a pendulum and making an inelastic collision find the kenitic engergy and the inital velocity"
2. Relevant equations
I found all the answers and I assume the experiment in the moon would yield the same kenitic energy " I know the gravety is less but I also assuming the height of the combination would rise higher than the earth therefore balancing the equation"

earth
"Vi= ((2*9.81*.0821)square-root )
Vi=1.27m/s

moon " assuming the gravity is half the earth (4.905m/s^2) and therefore assuming the pendullum is will go twice as height (.1642m)

Vi=((2*4.905*.1642)square-root)
Vi=1.27m/s

"I said the experiment being done in the moom with the same materials use in the earth would give the same Vi because less gravety would balance with higher "H" height.
