Answer to Problem 38RE
The answer:
Explanation of Solution
Given information:
The function is:
Calculation:
The velocity function, or the second derivative of the position function, is used to derive the acceleration function.
Therefore, the required acceleration is
(c)
To describe: The motion of the particle

Answer to Problem 38RE
The answer: The particle starts at 3 and is moving in the positive direction but decelerating until a position of
The particle then moves in the negative direction and is accelerating for
Explanation of Solution
Given information:
The function is:
Calculation:
From part
Set,
The particle is moving to the right from
From part
Set
So,
Therefore, the required the particle starts at 3 and is moving in the positive direction but decelerating until a position of
The particle then moves in the negative direction and is accelerating for
