Question

what is the speed of the book at 1.25 seconds?
speed of sliding book
0 m/s
0.5 m/s
1.0 m/s
1.5 m/s
question 11
which would you use to compare information collected by counting?
bar graph

Explanation:

Step1: Analyze the graph

Locate the \(x -\)axis value of \(t = 1.25\) seconds. Then, find the corresponding \(y -\)axis (speed) value on the curve.

Step2: Read the value

By observing the "Speed of Sliding Book" graph, when \(t=1.25\) seconds, the \(y -\)axis (speed) value is \(1.0\space m/s\).

Answer:

\(1.0\space m/s\) (the third option)
