All of the angles measure less than 90 degrees
All you have to do is addition. 2+5+4=11. Or you can break it down and go 2+5=7 and then 7+4=11. Or 5+4=9 then 9+2=11. Or 4+2=6 then 6+5=11.
So you want to plug in the height for h and solve for t
36 = -16t^2+14t+36
So you get 14/16 which simplifies to
7/8 seconds

Answer:
To find the acceleration we have its formula as
v-u/t where v is final velocity, u is initial velocity and t is time
So substituting the values,
0-40/5 m/s²
-40/5 = -8 m/s²
Thus the acceleration is -8m/s²
