A stream of water is shot with an initial speed of 2.3 m/s at a beetle on a leaf 3cm above the waters surface. If the fish aims in such a way that the stream of water is moving horizontally when it hits the beetle what is the launch angle.(adsbygoogle = window.adsbygoogle || []).push({});

Given:

Because the stream is moving horizontally then Vy = 0 m/s.

Ay = -9.8 m/s (gravity)

Displacement y (Dy) = 3 cm

Initial V = 2.3 m/s

How can i find the launch angle

Dy = Initial Vy * Time + 1/2(Ay)* Time*Time but dont know time or Vy

and i know nothing for x.
