Question

A bus makes a trip according to the position-time graph shown in the drawing. What is the average velocity (magnitude and direction) of the bus during each of the segments A, B, and C? Express your answers in km/h. The scale for the time axis is 1.5 h per increment, and scale for the velocity axis is 490 km per increment. (Indicate direction by the sign of the velocity.)

What is the average velocity (magnitude and direction) of the bus during each of the segments A, B, and C? Express your answers in m/h. The scale for the time axis ls 1.5 h per Increment, and scale for the velocity axls ls 490 km per Increment. (Indicate direction by the slgn of the velocity.) segment A km/h segment km/h segment C km/h Additional Materials Section 2.7

Explanation / Answer

Average velocity in this case will be equal to the slope of the line segment

a) Segment A

Average velocity = Slope = -490/1.5 = -326.667 km/hr

b) Segment B

Average velocity = Slope = +490/(2*1.5) = 163.333 km/hr

c) Segment C

Average velocity = Slope = 2*490/1.5 = 653.333 km/hr
