Question

The journey of a car is described by the displacement time graph. Which is the correct information regarding it’s journey?

• A. Vmax = 3.5 m/s
• B. Vavg =0.5 m/s
• C. Distance = 4 m
• D. Displacement = 10 m

Answer 1

Answer: (A), (B)

Vavg =0.5 m/s

• Total displacement = 4 m

• Total time taken = 8 seconds.

• Average velocity = total displacement/total time

• V_avg = 4/8 = 0.5 m/s

• Total distance = 7+3 = 10 m

• V_max = Maximum slope

V_max = (7-0)/(2-0) = 3.5 m/s
