ii) Use the fact that the two particles reach the same max height and solve the equation



iii)
This is pretty simple. It's a common type of question that I'm sure you know how to do. Remember to use the result in the previous part to get rid of any sin theta's or cos theta's. Hint: It says in terms of V and g.
