'B' is the correct choice.
BUT ... the angle of incidence is not the angle between the light ray
and the mirror. It's the angle between the light ray and the NORMAL
to the mirror. The 'normal' is the line that's perpendicular to the mirror.
Answer:
KE increases and PE decreases
Explanation:
The magnitude of the unknown height of the projectile is determined as 16.1 m.
<h3>
Magnitude of the height</h3>
The magnitude of the height of the projectile is calculated as follows;
H = u²sin²θ/2g
H = (36.6² x (sin 29)²)/(2 x 9.8)
H = 16.1 m
Thus, the magnitude of the unknown height of the projectile is determined as 16.1 m.
