Question 18: A horse starts from rest and gallops to a speed of 43.2 rm/\"hi in 1.53 5. Assuming the horse has accelerated uniformly. determine the distance it runs. x: Question 1 3: Given ' x is distance with rm v ' is velocity with units mfs ; . is time with units 5 . a is acceleration with units mfsz Then which equation(s} from the following list have units on the left side of the equals sign consistent with the units on the right side? (3)9: at (b}v3 = 20x2 (c) v = or + 1 m3 2 max = 35!, {G} x = g; + l or: 2 (g t = t! 2" a Question 20: An airplane, travelling North. has a landing speed of 79 mls. One it touches down. it has an 8?9 m long runway to reduce its speed to 19.7 m/s=. Compute the average acceleration of the plane during landing taking the direction of the planes travel as positive. a
