Hello there, I am having a lot of trouble solving a question with which I cannot even begin, I have tried making 2 equations and equation, but I just end up with some number = 0, which is of course wrong, here is the question.
QUESTION
A stone is dropped from the top of a tower. One second later another stone is thrown vertically downwards from the same point with a velocity of 14ms^-1. If they hit the ground together find the height of the tower.
I've managed to get that..
First rock
s = ?
u = 0
v = ?
a = 9.8
t = ?
Second rock
s = ?
u = 14
v = ?
a = 9.8
t = ?
Now where do I go from here? I've tried making 2 equations using the same base equation i.e. v^2 = u^2 + 2as with the different values and then equating them, which doesn't work.
Any help would be much appreciated, thanks.
