question 145

Multiple Choice

Solve.
-A projectile is fired upward from the ground with an initial velocity of 200 feet per second. Neglecting air resistance, the height of the projectile at any time $t$ can be described by the polynomial function $P ( t ) = - 16 t ^ { 2 } +$ $200 \mathrm { t }$ . Find the height of the projectile at $\mathrm { t } = 4$ seconds.

• A) \(644 \mathrm { ft }\)
• B) \(544 \mathrm { ft }\)
• C) \(736 \mathrm { ft }\)
• D) \(800 \mathrm { ft }\)
