No points will be awarded if I cannot understand what you have written, so please write clearly. Show all equations and calculations. There are four questions, each worth 5 points for a total of 20 points. You are taxiing on a heading of due West for 1500 m to the departure end of a runway in 3 minutes Make a) Draw a diagram showing the runway. Assume East is to the right. West is to the left. the origin of the coordinate system the departure end of the runway (5 points) b) What is the average velocity if positive displacements are measured towards the East? Answer (5 points) c) You taxi onto the runway, departing to the East. You are airborne in 10 seconds aftera displacement of 300m starting from rest. What is the average acceleration? Answer: (5 points) d) What is the take-off velocity? Answer: (5 points)Explanation / Answer
oart B "
Avg Velocity = total displacement/total time
Avg velcoity = (1500)/(3*60)
Avg velcoity = 8.33 m/s (ANswer)
----------------------------------
use S = 0.5 at^2
accleration a = 2S/t^2
a = (2 * 300)/(10*10)
a = 6 m/s^2 (answer)
-------------------------------------------
V^2 = 2* 6* 300
V = 60 m/s (answer)
