Amodel rocket is launched with an initial upward velocity of 215 ft/s. the rocket's height h (in feet) after t seconds is given by the following.

h=215t-16t^2

find all values of t for which the rocket's height is 97 feet.

Given:

h=215t-16t^2

the rocket's height is 97 feet.
Substituting the value of h.
97 = 215 t-16 t^2
Rearranging,
-16 t^2 - 97+ 215 t = 0
or 
16 t^2 - 215 t + 97 = 0
Solving the equation using quadratic formula:
We get two values of t.
t = 12.97
t = 0.46

Uh idk bossman just do it lol
