Question

The angle of projection of a particle is measured from the vertical axis as $ \phi $ and the maximum height reached by the particle is $ h_m $. Here $ h_m $ as function of $ \phi $ can be presented as

• A.
• B.
• C.
• D.

Hint:

Use the formula for maximum height in projectile motion. Since the angle is measured from the vertical, use \( \cos \phi \) instead of \( \sin \theta \).

Answer 1

The Correct Option is C

\( H_{max} = \frac{u^2 \cos^2 \phi}{2g} \)
