Answer:

y = 0.99m

Explanation:

This is a projectile launching exercise, let's start by finding the components of the initial velocity, using trigonometry

cos 0 = Vox / Vo

sin 0 =v_{oy} / Vo

Vox = vo cos

v_{oy} = I go sin

Vox = 15 cos 30 = 12.99 m/s

v_{oy} = 15 sin 30 = 7.5 m/s -

Let's find the time it takes to travel x = 18m

x = Vox t

t = x / Vox

t = 18/12.99

t = 1, 385s

at this point it is at a height of

y=v_{oy} - ½ gt²

y = 7.5 1.385 - 12 9.8 1.385²

y = 0.99m

therefore the camera must place the foot 99 cm from the ground
