anonymous · Answer

If we're not given the angles, are you trying to solve for the general case?

cp9454 · Answer

yes, angles are not given.

anonymous · Answer

Then, remember that $v_x=|v|\cos(\theta)$.

cp9454 · Answer

i know$$v _{x} and v _{y}$$

anonymous · Answer

You also have to consider the vertical component of their trajectories if they're not thrown at the same angle

cp9454 · Answer

i know that, you just rell me how to find the seperation

anonymous · Answer

How to find it? Sure: take each expression for each component, take the difference, and then find the norm of the resulting vector.

cp9454 · Answer

you have done and answer is coming

anonymous · Answer

I'm not sure what you mean...?

cp9454 · Answer

we have to use concept of relative velocity here
