A projectile is fired upward from the ground with an initial velocity of 300 feet persecond. Neglecting air resistance, the height of the projectile at any time t can bedescribed by the polynomial function P(t) = ­16t2 + 300

a.Find the height of the projectile when t = 1 second.
b.Find the height of the projectile when t = 5 seconds.
c.How long will it be until the object hits the ground?

Respuesta :

Answer:

P(t) = - ­16t*2 + 300t

For t = 1 second we have:

P(1) = - 16*1^2 + 300*1

P(1) = 284 ft

The height of the projectile after 1 second is 284 feet.

Step-by-step explanation:

Hope this helps :))
