Question

question 9 (1 point)
what is the velocity of the object in the graph at time 3 seconds.
velocity (m/s)
+10
0
-10
0 1 2 3 4 5
time (s)
o a 0 m
o b 1 m
o c 4 m
o d 10 m

Explanation:

Step1: Locate time on x - axis

Locate $t = 3$ s on the time - axis.

Step2: Find corresponding velocity

Read the value on the velocity - axis at $t = 3$ s. The velocity - time graph shows a horizontal line at $v=10$ m/s for all times from $t = 0$ s to $t = 5$ s. So at $t = 3$ s, $v = 10$ m/s.

Answer:

D. 10 m/s
