Step 1

Projectile motion has horizontal as well as vertical components of velocity. Consider the Newton’s equation of motion in vertical direction. At the maximum height of projectile, vertical component of velocity is zero.

Step 2

Projectile motion is entirely influenced gravitational acceleration alone. So replace *a* by –*g*.

Put 0 for *v _{y}* and –

Step 3

*voy * is the vertical component of initial velocity...
