Question 3 POST_UTME_ABU • 2018 • PHYSICS • objective

A projectile is launched from the origin with an initial velocity of 20 m/s at an angle of 30° above the horizontal. If the acceleration due to gravity is 9.8 m/s², what is the maximum height reached by the projectile?

Answer Options

A. \( \frac{20^2}{2 cdot 9.8} \)
B. \( \frac{20^2}{2 cdot 9.8} cdot \sin^2\( 30° \ \) )
Correct Answer C. \( \frac{20^2}{2 cdot 9.8} cdot \( 1 + \sin^2(30° \ \)) )
D. \( \frac{20^2}{2 cdot 9.8} cdot \( 1 - \sin^2(30° \ \)) )
Correct Answer
C
Correct Option:
\( \frac{20^2}{2 cdot 9.8} cdot \( 1 + \sin^2(30° \ \)) )
