# A target plane flies at 2100 meters. An antiaircraft gun fires a projectile with an initial upward velocity of 200 m/sec. Will the projectile ever reach the altitude of the target plane?

##### 1 Answer

NO, because Maximum height is only

#### Explanation:

From the given : height of the plane

From Physics,

The

To determine the maximum, we convert this parabolic equation to its Vertex Form by completing the square

simplify first

This is the vertex form

Maximum

This is not enough to hit the plane at 2100 meters

God bless.... I hope the explanation is useful.
