Question

Derive the expression for maximum height of a projectile​

Answer 1

Explanation:

1. if α = 90°, then the formula simplifies to: hmax = h + V₀² / (2 * g) and the time of flight is the longest. ...

2. if α = 45°, then the equation may be written as: ...

3.if α = 0°, then vertical velocity is equal to 0 (Vy = 0), and that's the case of horizontal projectile motion.
