Ответ:
The distance traveled by the particle before it stops is 41.06 m.
Explanation:
We can find the distance traveled by the particle using the following equation:
Where:
: is the final velocity = 0 (when it stops)
: is the initial velocity = 30 m/s
a: is the acceleration = -4t m/s²
t: is the time
d: is the distance
First, we need to calculate the time:
Now, the acceleration is:
Hence, the distance is:
Therefore, the distance traveled by the particle before it stops is 41.06 m.
I hope it helps you!
