Answer:
the projectile reached a maximum height of 27.6 meters in 2.4 seconds and it took 5.0 seconds for it to hit the ground
Step-by-step explanation:
to find the vertex you can find the axis of symmetry first
that equation is -b/2a
-19/-8 = 2.375
then you take this and plug it in
-4(2.375)^2 + 19*2.375 + 5
that gives you 27.5625
then you have to find when it hits the ground
you can factor to find this out
-4t^2 + 19t + 5
4t^2 - 19t - 5
4t^2 + t - 20t - 5
t(4t + 1) -5(4t +1)
(t - 5)(4t + 1)
t = {5, -1/4}
we can only take positive time so it took 5 seconds
the answer is the second one
