Well, that would depend upon when you let them go and from what height you dropped them! If you don't drop them at the same time, the one you released first will hit the ground first -- unless it was released from a greater height, in which case it may not! By now I hope you can see that your question left out a lot of important information. But I suppose you were assuming that both rocks were released simultaneously and from identical heights. In that case, they will both hit at the same time, unless one of the rocks has more air resistance than the other, which could cause them to hit at different times. But it's unlikely that two rocks you could hold would have very different air resistances, so both will strike the ground simultaneously, because the acceleration due to gravity is independent of an object's mass.
The rock that is denser
With a big rock.
SMALL.
moves small rock and hits it into big rock
It can be either. The kind of rock does not dictate size.
the effect is that if the rock is to big the it wont go far so you will need a small rock. but if you want a big rock then you will need a big sling shot and it has to be strong.
First, you have to jump into his spinning ball of rocks. If you do it right, one rock will hit him in the head. Then he starts lifting up the ground. If you put the big rock in the right place, he will lift up the ground where the rock is. IT will fly up in hit him of the statue and you put the handcuffs on him.
it stays the same but it depends on what kind of rock it is
i dont really know
on plant if small by rock is big
Move the big rock right under him then move out the way when he is about to lift up the ground. Its hard at first but you'll get :) ..i did.
Size does not matter, technique does
Big muscles first. Because if you do small ones first, by the time you start with the big ones you wont have enough energy. When you work your big muscles first, you use your small ones as well.
