a graph is presented below, representing an objects motion.
speed vs. time
which of the following times is the object at rest?
a t = 0 s
b t = 1 s
c t = 3 s
d t = 5 s

Explanation:

Step1: Understand object - at - rest condition

An object is at rest when its speed is 0. We need to find the time when the speed value on the speed - vs - time graph is 0.

Step2: Analyze the graph

Looking at the speed - vs - time graph, we see that the speed is non - zero for \(t = 0s\), \(t=1s\), and \(t = 3s\). At \(t = 5s\), the speed is 0.

Answer:

d. \(t = 5s\)
