Answer: 4 units
Step-by-step explanation:
The given position function:
, where t≥0.
To determine: Total distance traveled by the particle from 0≤ t ≤ 4.0.
At t=0,

At, t=4,

Total distance traveled by the particle from 0≤ t ≤ 4.0 = |42-38| units
= 4 units
Hence, the distance traveled by the particle from 0≤t≤4.0 is 4 units.
