The history of life in the geologic past as indicated by the imprints or remains of living thing is called FOSSIL RECORD.<span> It is the evolution that unfolded over trillion of years as natural and environmental interacts based on the natural selection. The fossil record is among the most popular evidences of evolution. It shows the way of living, the type of people, the survival struggles of the ancient people in the old times. All these types of remains are recorded that makes up the fossil record. </span>

Answer:
17.2 seconds
Explanation:
Given:
v₀ = 0 m/s
a₁ = 10.0 m/s²
t₁ = 3.0 s
a₂ = 16 m/s²
t₂ = 5.0 s
a₃ = -12 m/s²
v₃ = 0 m/s
Find: t
First, find v₁:
v₁ = a₁t₁ + v₀
v₁ = (10.0 m/s²) (3.0 s) + (0 m/s)
v₁ = 30 m/s
Next, find v₂:
v₂ = a₂t₂ + v₁
v₂ = (16 m/s²) (5.0 s) + (30 m/s)
v₂ = 110 m/s
Finally, find t₃:
v₃ = a₃t₃ + v₂
(0 m/s) = (-12 m/s²) t₃ + (110 m/s)
t₃ = 9.2 s
The total time is:
t = t₁ + t₂ + t₃
t = 3.0 s + 5.0 s + 9.2 s
t = 17.2 s
Round as needed.
Answer:
use a=v-u/t formula it will be correct
Its acceleration is constant.
