Answer:
1.75 seconds
Step-by-step explanation:
Lets apply the quadratic formula-
- 8 +_ (sqrt of 64 + 19.6)

-9.8
-8 +_ 9.1433
__________________
-9.8
x = 1.74931972 ( since x can only be positive in real life situations like when throwing a ball)
x = 1.75 rounded in seconds
Answer:
Step-by-step explanation:
h(t)= -8±√8^2-4(-4.9)(1)/2(-4.9)
h(t)=-8±√64-19.6/ -9.8
h(t)=-8±√44.4 / -9.8
h(t)=-8±6.6633325/ -9.8
h(t)= 0.14
The height will be 0.14
The time will be 2.02 seconds per meter
Hope that helps.
