Answer:8 I think, sorry it it is wrong
Step-by-step explanation:
1 2/5 + 3 1/2
= 7/5 + 7/2
= ((7x2)+(7x5))/(5x2)

=49/10
=4 9/10
Answer with Step-by-step explanation:
We are given that height of projectile after t seconds is given by

a.h(t)=144 ft






t-3=0
t=3
After 3 s, the height of the project will be 144 feet in the air.
b.h(t)=0




At t=0, the initial position of projectile
At t=6 s , the projectile will hit the ground.
