Question

One of the fireworks is launched from the top of the building with an initial

Answer 1

the equation is -16t^2+150t+50, the middle term being the upward velocity and the last term being the height it started at.
The vertex is at -150/-32=4.6875, and the height is 401.56 feet
Setting the equation equal to zero,
-16t^2+150t+50=0 or 16t^2-150t-50=0
t=(1/32) { 150 +/- sqrt (22500+3200)}, where sqrt (25700)=160.31
t=(1/32)310.31=9.697 sec or 9.7 seconds TIME TO LANDING 

0---50
1--184
2--286
3--356
4--394
5--400
6--374
7--316
8--226
9--104
10--has hit 

axis of symmetry is at vertex or t=4.6875

negative values would imply the rocket was rising up through the building.
