θ=60°, ux=10 m s-1, uy=? As tan θ=(uy/ux) ∴ uy=ux tan θ=10×√3 =10√3 m s-1

Q. A bird flies at an angle of $6 0^{\circ}$ to the horizontal. Its horizontal component of velocity is $10 m s^{- 1}$ . Find the vertical component of velocity in $m s^{- 1}$ .

$θ = 6 0^{\circ}, u_{x} = 10 m s^{- 1}, u_{y} = ?$
As tan $θ = \frac{u _{y}}{u _{x}}$
$∴ u_{y} = u_{x} t an θ = 10 \times 3$
$= 103 m s^{- 1}$
