Answer:15.78 m

Explanation:

Given

mass of apple m=12 g

launch angle
$\theta =78^(\circ)$

initial velocity
$u=18\ m/s$

For the projectile motion, maximum height is given by

$H_(max)=(u^2\sin^2 \theta)/(2g)$

Putting values

$H_(max)=(18^2\cdot \sin^2(78^(\circ)))/(2*9.81)$

$H_(max)=(324*0.956)/(2*9.81)=15.78\ m$
