**projectile motion question...please help**

hi peeps, I am reviewing the projectile motion stuff and for some reason I am finding this question really tricky so can anyone take me through this question or at least give me a hand?

The archer fish spits down a prey from overhanging foliage. If the inital velocity of the spit is u = 4.6m/s at an angle of 60 degrees to the surface of the water.

1. What is the height of a bug at the top of the trajectory?

2. How long has the bug got to escape the impending spittle?

3. The bug gets knocked off its branch with a horizontal velocity of 1.15m/s.Given that the horizontal dist. from the spitting position to the branch 0.94m, how far must the fish swim from its spoitting position to catch the fish as soon as it hits the water.

thanks
