Question

26. A bus moving along a straight line towards positive X-axis start from initial position Xi=0m at initial time ti =50m at final time tf=5sec. compute the average velocity of the bus at this intervals of time. A.5m/s B.8m/s C.10m/s D.12m/s

Answer 1

Interpret the data as the bus going from x_i = 0 m to x_f = 50 m in t_f − t_i = 5 s − 0 s.
Average velocity = Δx / Δt = (50 − 0) m / 5 s = 10 m/s.

Answer: C. 10 m/s.
