Question
Chapter 3.8, Problem 5E
(a)
To determine
To find: When the particle is speeding up and slowing down.
(a)
Expert Solution
Answer to Problem 5E
The particle speeds up on the interval (0, 1).
The particle slows down on the interval (1, 2).
Explanation of Solution
The given figure represents the velocity function of the particle.
It is identified from the graph that the velocity is positive on (0, 2) and is negative on (2, 3).
Also, observe that the graph increases on the interval (0, 1) and decreases on (1, 3). Thus, the acceleration is positive in the interval (0, 1) and negative in the interval (1, 3).
Recall the fact that the particle speeds up when the velocity and acceleration have the same sign and slows down when the velocity and acceleration have the opposite sign.
Therefore, it can be concluded that the particle speeds up on the interval (0, 1) as v and a have the same sign and slows down on the interval (1, 2) as v and a have the opposite sign.

- Calculate these limits. If the limit is ∞ or -∞, write infinity or-infinity. If the limit does not exist, write DNE: Hint: Remember the first thing you check when you are looking at a limit of a quotient is the limit value of the denominator. 1. If the denominator does not go to 0, you should be able to right down the answer immediately. 2. If the denominator goes to 0, but the numerator does not, you will have to check the sign (±) of the quotient, from both sides if the limit is not one-sided. 3. If both the numerator and the denominator go to 0, you have to do the algebraic trick of rationalizing. So, group your limits into these three forms and work with them one group at a time.
