Answer: The polynomial that describes the projectile's height is:
P(t) = - Â16t*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:
The height should be 284 feet.
Given that,
- A projectile is fired upward from the ground with an initial velocity of 300 feet per second
- Neglecting air resistance, the height of the projectile at any time t can be described by the polynomial function P(t) = Â[tex]16t \times 2 + 300t[/tex]
Based on the above information, the calculation is as follows:
[tex]P(t) = -16t\times 2 + 300t[/tex]
Here t = 1 Â
[tex]P(1) = - 16\times 1^2 + 300\times 1[/tex]
= 284 ft
